Abstract

The invention discloses a boiler system utilizing garbage incineration synthesis gas, which has small heat conversion efficiency loss and higher heat recovery efficiency. The boiler system comprises a boiler body, wherein the boiler body is provided with a cyclone combustion chamber, a furnace chamber a and a furnace chamber b, which communicate with one another; a water wall is arranged in the cyclone combustion chamber; a superheater is arranged in the furnace chamber a; an evaporator is arranged is the furnace chamber b; a steam drum is arranged at the top end of the boiler body; a steam-water inlet is formed in the steam drum; the steam drum is connected with a water inlet of the water wall through a first downcomer to output water; the steam drum is connected with a water inlet of the evaporator through a second downcomer to output water; a steam outlet of the water wall and a steam outlet of the evaporator are connected with a steam inlet of the steam drum to reflux high-temperature steam; a saturated steam outlet of the steam drum is connected with a steam inlet of the superheater through a pipeline to input high-temperature steam to the superheater; and a steam outlet of the superheater outputs superheated steam.

Description

technical field [0001] The invention belongs to the technical field of solid waste incineration treatment, and in particular relates to a boiler system for incinerating synthesis gas by gasification of waste. Background technique [0002] The existing waste treatment technologies mainly include incineration, sanitary landfill, composting, and waste recycling. Among the conventional waste treatment technologies, incineration has the advantages of obvious reduction effect, complete harmlessness, small land occupation, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. However, with the continuous improvement of environmental protection requirements at home and abroad, how to strengthen the control of secondary pollution is particularly important. Therefore, waste pyrolysis and gasification incineration technology is gradually pushed to the road of industrial application, especially fo...
