Abstract
The utility model discloses a 4t/h times high pressure boiler which comprises a boiler body, wherein a water cooling system is arranged on the boiler body, a chain grate is arranged in the boiler body and five independent wind chambers are arranged under the chain grate. Both sides of the lower part of the boiler body are provided with air inlets, a boiler chamber is arranged above the chain grate and the boiler chamber is communicated with a convection zone which is composed of convection banks. The convection banks are connected with an upper and a lower boiler barrels, and a front arch pipe is communicated with a front header tank and is communicated as a loop with the upper boiler barrel. Both side water-cooled walls are respectively communicated with a left and a right header tanks and are connected with the upper boiler barrel via a descending pipe so as to form two independent loops, a back arch pipe is connected with a back header tank and is connected as a loop with the upper and the lower boiler barrels and the rear part of the boiler body is connected with a coal economizer. The utility model has the advantages of reasonable structure and high combustion efficiency, rated capacity is 4t/h, and the utility model is suitable for the special gas use requirements of chemical industry enterprises.
