Problems solved by technology

[0007] The above known dry and wet feed entrained bed gasification equipment are all designed for large-scale gasification equipment (1000-2000 tons / day), and their designs are not compatible, that is, they can only be used in a single type state (dry or wet) system
In the case that the demand for use is not high, if the known large-scale gasification equipment is directly scaled down and manufactured, the problems and defects in the above-mentioned large-scale equipment will be more serious when the scaled-down equipment is operated. However, commercial gasification The operation stability required by the furnace should be quite high, and the instability or blockage of the feeding material cannot be tolerated.

Abstract

The present invention relates to a feeding system for a gasifying furnace. The feeding system comprises a coal chamber body, an exhaust device, an oblique air feeding device and a delivery pipe. The coal chamber body is provided with a side wall. The exhaust device is connected with the coal chamber body. The oblique air feeding device is arranged on the side wall of the coal chamber body. The coal chamber body is connected with the gasifying furnace by the delivery pipe.

Description

technical field [0001] The invention relates to a feed system of a gasification device, in particular to a feed system suitable for both dry and wet uses. Background technique [0002] In recent years, because the world is facing environmental protection and energy issues at the same time, the governments and industrial circles of various countries have attached great importance to the research and development of clean coal technology with high energy efficiency and low pollution. How to improve the efficiency of coal use and reduce coal pollution is the primary issue in the development of clean coal technology. Among various clean coal technologies, gasification technology has attracted the most attention. Various fuels such as coal, petroleum coke, biomass energy and waste can be used as feed materials, and the syngas produced can be Diversified applications, such as electricity generation, as fuel and conversion into chemicals, etc., so countries are actively developing ...
