Measures to improve the thermal efficiency of the boiler plant food which measures to improve the thermal efficiency of the boiler plant foods What? Many food factory in boiler production process, due to the thermal efficiency of the boiler has not improved, or thermal efficiency of the boiler has been in a low stage of words. For productivity improvement and waste of resources but also have a very large loss. So be sure to conduct a detailed understanding of how the method for improving the thermal efficiency of the boiler plant is for food. 1) The flue gas heat recovery techniques to reduce exhaust smoke heat loss of the main factors affecting the exhaust gas temperature is lost. The higher the exhaust gas temperature, exhaust heat loss will be. Now, when most of the new boiler factory is equipped with flue gas heat recovery equipment, such as economizers, half or full condensation condensing flue gas heat recovery device, these measures can effectively reduce the exhaust gas temperature and improve the thermal efficiency of the boiler. 2) reasonable control air-fuel ratio, to optimize combustion and reduce the loss of incomplete combustion when the heat losses and the excess air coefficient is too high, corresponding to the remaining inhaled cold air into the furnace, the remaining part of the cool air which does not participate in the combustion, but vain drained after being heated, the heat loss of exhaust gas is increased; cold air into the furnace as to continue to increase beyond a certain limit, the furnace temperature will drop, will not constitute a complete loss of combustion increases. When the excess air coefficient is too low, because the fuel can not get enough oxygen to completely burn incomplete combustion loss increases configuration. The prolonged severe incomplete combustion, boiler heating surface will result in carbon, influence the efficiency of heat transfer, exhaust loss continues to increase. Thus, the reasonable control of air-fuel ratio, exhaust heat loss q2 try to drop and incomplete combustion loss q3, is to improve the thermal efficiency of the boiler of the other key points.

Emergence of gas-fired boiler, only allows chemical companies to reduce pollution of the environment, can also improve production efficiency, reduce production costs, can be said to serve several purposes. It turns out, is the market development needs, will surely opened a new prologue for the development of the chemical industry.

Recently, Shaanxi Province, issued a "Boiler Air Pollutants Emission Standards" ( "Standards"), the "standard" in the concentration of air pollutants emission limits thermal power boilers and industrial boilers, we have developed a monitoring requirements.

Thermal power generation boilers including boilers of various capacities and various gas turbine capacity, fuel main types of coal, natural gas, oil, biomass, like other gas. Use gangue, oil shale, petroleum coke, fuel, sludge and other coal-fired power boilers reference emission limits fired boilers performed.

Industrial boilers including industrial boilers, various types of fuel capacity mainly coal, gas, oil, biomass, and so on. Boilers using coal, coal water slurry, coal waste, semi-coke, petroleum coke, oil shale and other fuel fired boilers performed with reference to emission limits. Using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.) with reference to the boiler exhaust gas boiler limits performed. Oil and gas dual-fuel boiler in accordance with the type of execution are oil-fired boiler and gas boiler emission standards. Other types of fuel mixed fuel boilers by performing more stringent emission standards.

Possible causes of Water shortage in Oil-fired Gas-fired Steam boilers

Water is the main medium for generating heat energy in boilers. During the operation of steam boilers, the drum (pot) contains and maintains a certain amount of water, which makes the steam pressure and boiler water level relatively stable, and is also beneficial to the natural circulation of boilers and the separation of steam and water. It is the basic condition for safe operation of the boiler.
