Industrial gas fired hot water boiler outlook is do i think the oil fired hot water boiler. They've already some same features as below:
Fuel gas hot water boiler is unlike coal-fired hot water boiler, it will need make use of burner to inject fuel into hot water boiler furnace. Gas fired hot water boiler take burning chamber without using grate. As the combustion of fuel gas hot water boiler doesn't produce ash and slag, which means this kind of hot water boiler could be operated without sludge discharge facilities. If oil spraying into furnace when combined air in the certain range or go out, it could be an easy task to explode. Therefore the fuel gas hot water boiler always take automatic burning and control systems. The structure of fuel gas hot water boiler is compact, about small hot water boiler, ventilation, water supply, control and auxiliary equipment are all set in a chassis. Large and medium-sized may also be assembled at factory. Main pressure parts and connect ways are mentioned below:
1.The primary pressure aspects of fire tube hot water boiler: hot water boiler shell, tube plate, furnace, smoke tube;
2.The primary pressure areas of water tube hot water boiler: steam drum, water wall, hot water boiler tube bundle, coil, header;
3.The text methods for fuel gas hot water boiler main pressure parts: mainly for welding, certain parts could also be expanded joint;
Combustion characteristics of gas fired hot water boilers:
Burning high calorific importance of gas will need a lot of air, for making gas fully burning requires to mix with lots of air. There isn't any fuel atomization and gasification process within the gas combustion process. The way of mixing with air and gas has great influence for the strength with the combustion, flame length and flame temperature. As outlined by different mixing mode, fuel gas combustion method can be divided into three types:
1.Diffusion combustion: the combustion way is not combined in advance, gas and air...
