Back nine, Henan gas boiler trip or normal shutdown to be purged immediately ventilate the furnace, the furnace unburnt coal dust and combustible gas pumped in a timely manner. And promptly shut down the boiler supply and return oil total gate manually to prevent leakage of fuel oil gun into the furnace. Ten, Henan gas boiler shutdown purge gun ban mill and pulverized coal into the furnace exhaust.

By the end of 2016, the State Council issued separately "" Thirteen Five "environmental protection plan" and "" Thirteen Five "energy-saving and environmental protection industry development plan", environmental planning and environmental protection industry to make guidance. During the two sessions this year, environmental protection is also a hot topic. Policy of continuous progress, and constantly increase investment in environmental protection efforts, more and more industries engaged in environmental construction. In the pharmaceutical industry, pharmaceutical equipment associated with its environmental protection has also been vigorously sought after by the market, the drug manufacturing must seize the favorable policies, increase research and development of energy-saving, environmental protection, pharmaceutical equipment.

In the pharmaceutical industry, industrial steam and pure steam is essential production conditions, mainly heating and apparatus for sterilizing products. The main steam from natural gas and other fuels to generate heat in the boiler, and the boiler consumes a lot of fuel per year. Currently, many enterprises will be condensed water vapor produced direct emissions, which not only pollutes the environment, but also lost a lot of heat and precious water resources. If we can be recycled, either generate economic benefits, can also protect the environment.

For a long time, boiler manufacturing industry has been committed to upgrading boiler welding technology to improve the level of boiler manufacturing technology, especially in recent years, domestic production of boiler equipment companies are active in technological innovation, and the introduction of new equipment, new technology to promote advanced welding to accommodate boiler capacity, and the parameter variations furnace, boiler meet the complex structure of the new materials and the welding member boiler.

Experts said boiler technology has made some progress, but the low efficiency of industry resources are distributed, disorderly market competition, product less competitive and other issues also plagued the entire boiler industry. Boiler welding technology, while progress has been made, but the level of automation of welding part of the product to be improved, welders welding quality is good or bad is still dependent on the technical level.

Market demand, the major boiler manufacturers are actively cooperate with professional welding equipment manufacturers to develop new welding equipment and welding technology. In recent years, China's major boiler plant are actively carry out technical transformation, the introduction of new technology and new equipment, and actively implement new advanced welding technology, adapt to changes in the parameters of boiler capacity and the furnace, boiler and boiler components to meet the complex manufacture of new materials requirements.

Insiders said that in terms of stabilizing the economy and achieve long-term sustainable development, energy saving and environmental protection industry is an important force. After the new GMP implementation on some equipment and production conditions put forward higher requirements, how to meet the production requirements of the premise, as far as possible to reduce energy consumption, which has become a headache problem of large pharmaceutical companies. Use energy boiler system is an effective way in the pharmaceutical industry to achieve energy saving, reduction of pollutant emissions fog.

Changing and blessing, natural gas fuel development and application of national energy saving policy of energy supply system will enter a period of rapid development, coal-fired industrial boilers will gradually withdraw from the center of town. Launched around the "coal to gas" and other policies is to verify this fact. In the context of social development, boiler manufacturing industry must adhere to market-oriented strategy to develop science and technology as a weapon boiler, under the guidance of relevant national policies, enterprise architecture and product structure adjustment, to obtain long-term survival and future development.

Three tempering tube hot water boiler installation and commissioning of the structure outlined hot water boiler is fast loading of the internal combustion level. A second high temperature flue gas successively washed roots and refluxed for three breathing tube, the smoke chamber into the atmosphere through the chimney. Gas hot water boiler equipped with the world famous burner, combustion using automatic adjustment, automatically adjust the water supply, the program starts, automatic control and other functions. The boiler has a compact, safe, reliable, easy to operate, installation speed, low pollution, low noise, high efficiency. Widely used in enterprises, hotels, hospitals, office buildings, civil construction and other industrial steam, life, mining and other facilities. This installation requires fast speed boiler installation, installation is very simple, the boiler does not require special ground base, only enough to withstand the ground to power. 1. Install the water supply line requires the highest level reservoir, generally not critical, the high from the ground to the reservoir tank, underground tank of water should be kept clean. Pool water outlet. For wire entrance filter water supply line. 2, the straight cross-section is mounted, the return pipe return pipe to be 0.5 meters above the bend radius should be 4 to 5 times the diameter of the pipe, the pipe should be installed at the highest automatic steam valve to prevent the steam from the pipe loop. At the same time, the general requirements of the highest level possible reliable reserve pool. When the boiler water level is below the line, the water will flow into the boiler when the next time you start. Filter wire 3 should be installed at the outlet (i.e., the inlet pipe) of the pool. Installation requires a supply line Burner fuel hose has two interfaces, and for the oil return into the oil, as long as the boiler return oil chamber and the oil corresponding feed pipe. Dedicated hydraulic system from the boiler tank to the burner pump port, an operation instruction for the burner 4 is provided. Chimney straight chimney installation requirements. The length of the chimney should not be too long, the stack height should be less than 5 meters. Chimney height should comply with relevant standards. Chimneys should be added raincap and smoke. Weight not directly on the boiler chimney host chimney 5, hydrostatic test shall be carried out after the installation of boiler water pressure test supervisor. Pressure test before proceeding to deal with internal boiler inspection, hydrostatic test pressure MPa, during hydrostatic testing, water pressure should slow down. When the pressure rises to 0.1MPa, the water pressure should be increased to 0.1MPa. When the ambient temperature is higher than 5C, hydrostatic test should be carried out; when the temperature is lower than 5, should be protected from freezing water pressure test. Hydrostatic test water is generally 20-70.6, should be as light fuel oil or gas oil (China) as the fuel, the fuel oil is generally heated to 100 deg.] C, a viscosity less 30E. Oil Qbw = 10200Kcal / kg LHV viscosity of the oil is lower than at 50 ℃ 200E, at less than about 80 ℃ 200E, 50e is less than the heat value of natural gas Qbw = 8550Kcal / kg LPG Qbw = 22000Kcal / kg.

Improve the thermal efficiency of the process wns gas boiler, oil-fired boiler which chemical incomplete combustion heat loss and mechanical incomplete combustion heat loss. Because almost no ash after combustion of the gas boiler, solid and liquid fuels without mechanical incomplete combustion, there is no need to consider the mechanical incomplete combustion of the gas boiler heat loss. In all heat losses, heat losses have tremendous proportions, when the high thermal efficiency of boilers, heat losses so the total loss of the main heat losses of fuel gas-fired boiler flue gas heat loss is the exhaust gas temperature and For air excess factor. When the exhaust gas temperature decreases, high thermal efficiency can be obtained, for example, a conventional three-pass 1th steam boiler, furnace used in the past straight and smooth smoke tube, must increase the heating surface is arranged to make the exhaust gas to an acceptable degree, the theoretical discharge around the smoke heat loss. Potshell causing significantly increased diameter, wall thickness increased, greatly increased metal consumption, thus further reducing the exhaust gas temperature should be greatly restricted. From the aspect of heat transfer is not only now consider only the heated area, the use of new technology enables heat transfer performance significantly increased, the difference between the heat transfer overcomes the disadvantages of the past performance of the boiler, so that the exhaust gas temperature decreases, the structure is more compact. Center back boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas wns improve thermal efficiency of the boiler as the oil, gas fuel burn easily wns type gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature. Separation type condensing gas boiler is out of the main boiler heating surface, the installation of the condensing heat exchanger. In one aspect of the flue gas absorption can significantly reduce the smoke temperature, reducing heat losses, on the one hand the absorption of part of the potential condensing water vapor released, increasing the effective use of heat of the fuel. Ash cleaning, to ensure that the heating surface of the scale wns boiler thermal efficiency of the boiler, the presence of soot fouling and heat transfer resistance increases, reducing the heat transfer effect. The thermal conductivity of the scale and soot is almost of the same order of magnitude, with the increase in scale, soot, the exhaust gas temperature rapidly increases, the thermal efficiency is significantly decreased. So, keep the boiler heating surface inside and outside clean, efficient heat transfer, thermal efficiency and to ensure the safe and economic operation of boilers, boiler fuel gas-fired boiler ash cleaning is required.
