Multi-hearth full-anti-burning coal gasification boiler

Abstract

The invention discloses a multi-hearth full-anti-burning coal gasification boiler, belonging to the technical field of boilers and solving the problems of substandard flue gas, inconvenient operation and potential safety hazard existing in a traditional coal gasification boiler. The multi-hearth full-anti-burning coal gasification boiler comprises a plurality of anti-burning gas generating chambers which are respectively provided with coal-adding furnace doors, the upper parts of the anti-burning gas generating chambers are communicated through anti-burning communication holes, the lower part of each coal-adding furnace door is respectively provided with an anti-burning grate and an ash-poking hole, a combustion chamber, primary high-pressure air vents and a water sealing pool are arranged below the ash-poking hole, the combustion chamber is provided with a fire outlet communicated with a heat-absorbing area, a slag outlet is arranged below the fire outlet, secondary high-pressure blast is arranged above the anti-burning gas generating chambers, the heat-absorbing area is internally provided with a plurality of heat-absorbing water pipes, and flue gas outlets are arranged above the heat-absorbing area. The invention increases the anti-burning area, enables flue gas to be further environment-friendly, is convenient to operate, improves the flow velocity of the flue gas and lessens the potential safety hazard.

Description
