Heating gasifying furnace

Abstract

The invention provides a heating gasifying furnace. The heating gasifying furnace comprises a furnace chamber; a gasifying pipe is arranged inside the furnace chamber; the bottom of the gasifying pipe is open and the top is closed; the surface of the gasifying pipe is provided with gasifying holes which are communicated with the interior; the gasifying holes are uniformly formed in the gasifying pipe or the number of the gasifying holes which are formed in the top is larger than the number of the gasifying holes which are formed in the bottom; an opening at the bottom of the gasifying pipe is connected with a ventilation pipeline; a valve which can control the ventilation quantity is arranged on the ventilation pipeline; the number of the gasifying pipe is at least one; the gasifying pipe is vertically or obliquely arranged inside the furnace chamber; the furnace chamber is connected with a flue; a water tank is arranged outside the flue; the flue comprises a heat source concentration box which is arranged at the bottom of the water tank and a heat collection pipe which is perpendicular to the heat source concentration box; the top of the heat source collection pipe is connected with a chimney. The heating gasifying furnace has the advantages of being high in energy utilization rate, good in gasifying effect and full in coal combustion, well utilizing heat and being low in manufacturing cost, simple in technology, convenient to operate and high in environmental performance.

Description

technical field [0001] The invention relates to the technical field of stoves, in particular to a stove integrating heating, energy saving and environmental protection, specifically a heating gasifier. Background technique [0002] As we all know, coal is still used for heating in northern rural areas in winter. By burning fossil energy—coal, a large amount of smoke and dust will be generated during the coal combustion process. People's health, at the same time, a large amount of smoke and dust is discharged through the flue, resulting in insufficient coal combustion, low energy utilization rate, and serious energy waste. [0003] At present, with the continuous improvement of heating furnaces, heating furnaces with gasification tubes have also emerged as the times require, and have been affirmed and recognized by the market. The preparation process of heating furnaces with air injection holes added to the furnace and gasification tubes is complicated, especially It is the ...

[0002] As we all know, coal is still used for heating in northern rural areas in winter. By burning fossil energy—coal, a large amount of smoke and dust will be generated during the coal combustion process.

[0003] At present, with the continuous improvement of heating furnaces, heating furnaces with gasification tubes have also emerged as the times require, and have been affirmed and recognized by the market. The preparation process of heating furnaces with air injection holes added to the furnace and gasification tubes is complicated, especially It is the ventilation hole on the furnace, which is easily blocked by coal powder, which affects the gasification effect of the heating furnace, and the later maintenance and repair are troublesome, and a large amount of heat is directly discharged into the atmosphere through the flue, resulting in energy consumption. waste. In addition, due to the high manufacturing cost of the current gasifier, the selling price is relatively high, and the market share is not very high.
