The hot water boiler system has large resistance and insufficient air supply. The reason is that the fuel particles are mixed, the pulverized coal occupies the lump coal gap, and it is squeezed by the gate when entering the grate. The gas hot water boiler has the remarkable features of environmental protection, energy saving, safety, and automatic operation. It is very convenient to use. In addition, due to the economic operation and policy encouragement, the gas hot water boiler is more and more popular.
Biomass boilers: horizontal biomass boilers, vertical biomass boilers. Biomass heat-conducting oil furnace, biomass steam boiler, biomass hot water boiler, biomass heat-conducting oil furnace. The gas-fired steam boiler adopts a lower-burner method, a two-return structure, sufficient fuel combustion, stable boiler operation and small footprint, and a spoiler inserted in the smoke pipe, which slows down the exhaust rate and increases the heat exchange capacity. The boiler has high thermal efficiency and reduces User fees First of all, this big coal cannot be burned through.
During the slag discharge, there was still a fire, and the slag retaining part was burned, and the carbon content of the residue was high; the second was the serious leakage of pulverized coal; the third was the large resistance, which increased the load of the blower and the induced fan, and the energy consumption was high. The furnace temperature is low, the coal quality is poor, and the combustion conditions are poor. The furnace temperature is low and sometimes even goes out. A large amount of unburned materials and ash powder blocked the economizer and air preheater, leaving the furnace in a positive pressure combustion state. Part of the heating surface of the reheater is set in the high smoke temperature area of the hot water boiler, which greatly increases the heating area required by the superheater.
In order to reduce the flow resistance of the working fluid through the heater and improve the rigidity of the tube, the superheater uses a tube with a larger diameter. In order to improve the radiant heat absorption rate of the superheater system and stabilize the steam temperature characteristics of the superheater, a radiant screen superheater and a semi-radiation rear screen superheater are set in the upper part of the boiler hearth. Separator superheaters are arranged along the width of the furnace. Each superheater is composed of a small screen, which not only increases the role of radiant heat transfer, but also blocks the rotating smoke stream to reduce the furnace entering the human superheater. Flue gas temperature deviation in wide direction.
