Vietnam 1 Ton Gas Steam Boilers


Vietnam 1 Ton Gas Steam Boilers

You know how the boiler works? Boiler parameters is a main boiler performance indicators, including the boiler capacity, steam pressure, steam temperature, water temperature and the like. Boiler capacity available rated maximum continuous evaporation or evaporation is represented. Rated evaporation under a predetermined outlet pressure, temperature and efficiency, the amount of steam per unit time of continuous production. Maximum continuous evaporation under a predetermined outlet pressure, temperature, per unit time the maximum continuous amount of steam produced. Steam pressure and temperature parameters including vietnam 1 ton steam boilers, generally refers to a superheater, superheated steam pressure and temperature at the outlet of the reheater and superheater if no reheater, saturated steam pressure and temperature at the outlet of the boiler refers. Refers to a water temperature of the economizer inlet temperature, inlet temperature refers drum without economizer. Boilers can be categorized in different ways. Boiler use can be divided industrial boilers, utility boilers, marine boilers and boiler locomotive; by the boiler outlet pressure can be divided into low, medium, high pressure, high pressure, sub-critical pressure, the supercritical pressure boiler; boiler and by water flue gas flow path can be divided into the fire tube boilers, fire tube boilers and water-tube boilers, fire tube boilers and wherein the fire tube boiler and collectively shell boiler; press cycle can be divided into natural circulation boiler, auxiliary boiler cycle (i.e., forced-circulation boilers), and the combined circulation boiler once-through boiler; by combustion, the boiler chamber into the burner, and boiling Stoker furnace. Water vapor system, feedwater heated to a temperature in the heater, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the water wall downcomer inlet header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam from the superheater to the upper stream drum, continue to become superheated steam endothermic certain temperature (most of the current 300MW, 600MW unit main steam temperature is about 540 ℃), and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere.

Such as the use of coal fired boilers, coal heating value 5500Kcal / Kg (in terms of standard coal) around, (coal prices have continued their upward trend in the market price of 460 yuan per ton, and the purchase and sale channel is not smooth, to control the current energy under rotten mining waste and serious situation, the price of coal have continued upward momentum). 10t vietnam 1 ton steam boilers steam coal consumption per ton of 0.2 ton, the price of 92 yuan. The hot gas is 8000kcal / Nm3, the price of natural gas per cubic 2.0 million, according to gas consumption per ton of steam gas consumption 80Nm3, the price of 160 dollars.

Different natural gas vietnam 1 ton steam boilers energy-saving measures as well as gas-fired boiler with environmental issues become more critical, more and more people are concerned about the importance of the environment for our development. Today, gas steam boilers in industrial production is very common, how to reduce the energy consumption of gas steam boilers, which we have been explored. We can take the following measures in natural gas steam boiler operation for energy. 1, the amount of steam needed for industrial production of a reasonable choice, and the number of the rated power station boiler steam boiler gas, in both cases the higher the degree of matching with the actual exhaust gas loss is smaller, the obvious energy saving. 2, the fuel in contact with air: fuel amount so that an appropriate amount of air and the optimum composition ratio of combustion, this would both improve fuel combustion efficiency and reducing emissions of polluting gases, energy to achieve the dual goals. 3, reducing the temperature of the exhaust gas steam boiler: the temperature of the boiler flue gas to reduce the effective use of exhaust heat generated in general, the efficiency of the boiler used is 85-88%, the exhaust gas temperature is 220-230 ℃. If the setting of energy-using the exhaust heat or the like, the exhaust gas temperature falls to 140-150 deg.] C, the boiler efficiency can be increased to 90-93%. 4, recycle heat from the boiler blowdown water: water using continuous blowdown heat by heat exchange, in addition to improving water temperature itching water to achieve energy saving gas steam boiler. At the same time, measures energy-saving gas steam boiler can also be reasonably recovered condensate heating system, and the heat of the condensate water recycling. It is different from the gas boiler and gas boiler: 1. Gas circulating fluidized bed combustion boiler coal by crushing device by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx discharged from the flue gas the atmosphere, pollute the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions relative gas boiler gas boiler, SO3, NOx is much less. 3. Usually ventilation negative pressure combustion gas boiler, the combustion process is to group together to complete the mating with the mating blower and induced draft fan, the coal combustion process, requires a lot of air and the furnace wall due to the leakage of the flue, the excess air coefficient of up to between 2.1-2.5. Gas boiler combustion slightly positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion flue and the furnace wall, the flue outlet air ratio operation may 1.05-1.2.4. Fuel explosive gas boiler combustion safety, the furnace explosion hazard unlikely to occur. The gas-fired boiler in the explosive concentration limits encountered fire will explode. More dangerous. 5. Gas boiler control difficult due to coal boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to the operating parameters of the boiler load is large. Less impact on the factors of the gas boiler, the burner may be adjusted according to the size of the load valve, easy to achieve automatic control.
