Structure Of Gas Fired Boiler

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.

After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, and gas-fired attention and widely used, broke the burning coal structure of fired boiler "thriving" situation. With respect to polluting coal-fired boilers and oil-fired boilers, gas boilers use of clean energy - natural gas, less pollutant emissions, higher energy efficiency, in general, more cost-effective. Here follow the fast boiler together to understand the pros and cons of specific natural gas boiler it.

Method of reducing the exhaust gas temperature of the structure of fired boiler which: standard boiler exhaust gas temperature: between the boiler flue gas temperature of 200-230 deg.] C in accordance with conventional design national standard thermodynamic calculation boiler design requirements. Conventional exhaust gas temperature selected reasons, coal fired boiler combustion process will produce a certain amount of SO2, and SO2 below 170 ℃ will bind and generating flue gas H2O H2SO4 sulfuric acid, H2SO4 sulfuric acid and will form boiler heating surface of tail corrosion, thereby reducing the life of the boiler, conventional coal-fired boiler exhaust gas temperature is higher than 200 ℃. Temperature is high energy loss and more, is not conducive to energy saving. Cooling measures taken to ①, the economizer application: increasing the boiler economizer (economizer) of heat transfer area, larger than the conventional take about 1-2 times the flow cross sectional area economizer structure, effectively reduce smoke flow rate, to strengthen the heat transfer efficiency, reduce exhaust gas temperature; ②, air preheater applications: pipes connected to the air preheater economizer disposed, the apparatus can effectively increase the temperature of the combustion air, improving the ignition of the fuel condition. Very beneficial to the boiler combustion conditions. ③, adjust bidirectionality combustion system, a boiler originally designed for fuel specifications have some flexibility, different media in effect outside the combustion process are different, adjusting the embodiment, with the economizer and the air preheater using, the temperature of the boiler exhaust emission control at a suitable temperature, that make full use of heat energy, but also to ensure the integrity of the structure and function of the relative equipment, environmental protection, energy saving, security and development is the social responsibility of all of us for a rational design of industrial structure boiler, thermal efficiency is relatively high, its emissions would be relatively low temperatures, so we must be careful when choosing a boiler boiler property report form.

Operation of the gas structure of fired boiler has what measures? Gas-fired boiler in many large factories or companies which, basically is a kind of device can see, of course, such a device is actually in the process of actually running, more or less have some of their own operating standards, from the current situation, when they run have more to do security measures. So what are run gas boiler measures at run time? (1) After a series of gas-fired boiler inspection, maintenance, basically in the process of running to them in accordance with the relevant requirements to run, there will have a lot of protection, even if they want to determine the importance of the protection of the entire work. (2) gas-fired boiler in the process of ignition, more or less likely to occur will require some regulations, such as they might meet some of the fuel, but the fuel pressure in the whole process of evaporation or mist, more or less will meet some of stroke, some extent, when the entire examination will also return to substantially a normal state, they energize the disable signal is short, when the flow rate of the whole is greater than a single second branched oil gun 0.65 kg when it should launch this gun running. (3) gas-fired boiler at the time of ignition, be sure to pay attention to look at all of the furnace temperature, the temperature inside look at the major, and the entire main steam pressure in the process of rising more or less there will be some obvious favoritism, or the case of speech do not rise, so then we should immediately go to the examination of fire tank. in addition, if found throughout the fuel into the furnace did not catch fire, it would tightly shutdown.
