Popularization of knowledge about oil fired hot water boiler

The oil fired hot water boiler is a shell type three way, full wet back structure The fuel is burned under slight positive pressure in the furnace tank The high-temperature flue gas enters into the threaded flue gas tube bundle through the back combustion chamber along the furnace tank, and enters the second tube bundle through 180 ° turning of the compressed front flue gas box, and then discharges into the atmosphere after passing through the heat exchanger The oil fired hot water boiler adopts the design idea of three-way structure with center symmetry, and designs the three-way atmospheric hot water boiler with large capacity The main features of the boiler Zui are: the center of the drum is symmetrical, the boiler adopts the full wet back structure, with the structure of the largest inner drum and eccentric fire box, which is conducive to the expansion of sufficient radiant heating surface The convective heating surface is composed of the second return and the third return tube bundles The front tube plate of the regenerative chamber is connected with the furnace tank The second return and the third return turn smoke chambers form the front smoke box, where the smoke temperature is below 500 ℃ Therefore, the structure of the front smoke box adopts the fire-resistant insulation material of light structure The water mixing device is set in the inlet of the boiler return water The return water first washes the pipe bundle of the flue gas pipe, and then contacts the furnace tank, which improves the water temperature of the return water contacting the furnace tank The phenomenon of local boiling is avoided Horizontal oil fired hot water boiler adopts corrugated tank, threaded smoke pipe and full-automatic welding technology, which greatly improves the service efficiency, service life and safety performance of the boiler The oil fired hot water boiler has the following characteristics: 1 Increase the radiation heat exchange area and improve the thermal efficiency; 2 Change the quasi rigid structure into the quasi elastic structure to effectively eliminate the stress; 3 High fuel burn out efficiency to ensure that the fuel can fully burn
