CN201407803Y - Dual purpose energy-saving plumbing boiler for molded coal and bulk coal - Google Patents

Abstract

An energy-saving plumbing boiler comprises a smoke removal channel heated on the inner pipe wall, a rolling fire grate, a water outlet, a water inlet, an ash removing opening, a deslagging hole, an air inlet, a bulk coal feeding port, and a molded coal feeding port. The energy-saving plumbing boiler is characterized in that the smoke removal channel heated on the inner pipe wall is arranged insidethe boiler. In the utility model, the rolling grate enables the molded coal to enter the deep part of a firebox for combustion since the smoke removal channel heated on the inner pipe wall is adopted, thereby effectively expanding the flame path and improving the heating efficiency.

Description
