10 15 mw coal fired power plant boiler

Gas 10 15 mw coal fired power plant boiler energy-saving programs: from "under the dome" to "Battle of the sky", efforts to promote China's environmental protection policies become more stringent, "coal to gas", "coal to electricity" and other energy-saving boiler has also become a hot item. Industrial coal-fired boilers, coal-fired boilers civilian or eliminated, or demolition transformed into energy saving gas boiler.

Autumn and winter cold season is heating the peak of the northern city of Tianjin, with the heating period, fog, haze and other inclement weather has cropped up, as also the people a "blue sky" always in a good living environment, inside of Tianjin low-emission coal-fired 10 15 mw coal fired power plant boilers reform process without delay. To improve the situation of air pollution, Tianjin start the "Blue Sky Project" plans to cooperate with the fast boiler, gas boiler will invest billions of dollars in coal-fired boilers within the city as a clean fuel such as natural gas as raw material.

2.Biomass fuel fired only and mixed with coal fired, more economic and more flexible.

3.Adopting a unique heating surface layout, boiler corrosion resistance performance enhancements, more secure and more reliable.

4.Biomass fuel crushed before getting into the furnace, conveying system debugging, reorganizes, running more stable more fluid.

Today I saw that when the capacity is the same, the furnace of the oil-fired 10 15 mw coal fired power plant boiler is smaller than that of the coal-fired boiler. Why? The specific reasons are as follows: the size of furnace volume, after the boiler capacity is determined, mainly depends on the volume of heat load. The size of the volumetric heat load is mainly determined by the type of fuel. After the fuel enters the furnace, it will take a certain amount of time to burn out. Fuel is usually required to burn out before it leaves the furnace. It is obvious that pulverized coal will burn longer than oil, that is, the flame of coal combustion will be longer than that of oil. In order to ensure the long-term safe operation of the boiler, it is necessary not only to prevent the slagging of the boiler, but also to make the temperature of the flue gas at the furnace outlet begin to change compared with the ash in the flue gas The temperature is 50 ℃ lower than 100 ℃ to prevent slagging at the furnace outlet and subsequent convection heating surfaces. The ash content of coal is more than that of coal-burning furnace, and the flue gas temperature of furnace outlet is 1050 ℃ and 1100 ℃. There is no danger of slagging in the furnace because of the low ash content in the oil, and do not consider the slagging problem of the slag discharge tube at the exit of the furnace, so the smoke temperature at the exit of the furnace can be higher.
