Fuel consumption is the main factor affecting the operation cost of the boiler. The higher the fuel consumption, the less energy saving the boiler is, the more money it costs, which is harmful to the enterprise.And the main factors that affect the fuel consumption is the operation of the boiler efficiency, on the market at present most of the steam boiler efficiency in 60-70%, and zhengzhou published fast industrial boiler steam boiler equipment using a variety of energy conservation and environmental protection technology such as condensation, FGR, will increase the operation efficiency of the boiler to more than 98%, higher than that of ordinary boiler,Therefore, the energy saving effect is also very significant.2 tons of oil and gas dual purpose steam boiler fuel consumption per hour can be controlled at about 140 cubic meters/natural gas.
Here, Zhengzhou Fangfast Boiler Factory also reminds us that we should pay attention to the state of the furnace in the process of boiler operation.
There are many reasons for coking in the furnace of the boiler, which are generally as follows:
(1) the nature of ash.The higher the melting point of ash, the less likely it is to coke.Conversely, the lower the melting point, the easier it is to coke.
(2) The composition of the surrounding medium also has a great influence on coking.In the combustion process, due to insufficient air supply or poor mixing of fuel and air, the fuel does not achieve complete combustion. The incomplete combustion will produce reducing gas, and the melting point of ash will be greatly reduced.(3) improper operation, so that the flame deflection or the primary and secondary wind is unreasonable, the primary wind speed is too high, the particles are not completely burned, and in the high temperature softening state adhere to the heating surface to continue burning, and the formation of coking.
(4) the furnace volume heat load is too large.When the boiler runs beyond the force, the temperature of the furnace is too high, and the ash particles reach the water-cooled wall surface and the furnace outlet, they can not get enough cooling, thus causing coking.
(5) soot blowing and coking are not timely.Causes the heating surface wall temperature to rise, thus causes the heating surface to produce serious coking.
