Technology combined application method of brown coal gasification furnace and combustion heat gas hot-water boiler

Abstract

The invention discloses a technology combined application method of a brown coal gasification furnace and a combustion heat gas hot-water boiler. The purpose of the invention lies in that through the adoption of the method, a direct combustion manner of coal for a long time can be changed, and a coal utilization manner is changed from a conventional utilization manner of being not clean, low in combustion rate and high in pollutant discharge quantity into a manner that coal is converted into a clean, efficient and environmental-friendly energy source for utilization. A technology system mainly comprises a brown coal gasification furnace body, a single hopper lifting automatic coal feeding mechanism, an automatic slag removal and ash discharge mechanism, a cyclone dust collector, a combustion heating gas hot-water boiler, a heating gas combustor, a water-sealed valve and the like. The gas making technology of a gas generation furnace is used, so that solid fuel coal is converted into combustible gas fuel, proximity docking and combined application of the combustible gas fuel and combustion heat gas hot-water boiler is realized, the purpose that the gas can be used after being produced is achieved, and the technology combined application method not only is energy-saving but also is environmental-friendly.

Description

[0001] Technical field: [0002] The invention relates to a combined application method of a lignite gasifier and a combustion hot gas hot water boiler, in particular to a one-to-one combined application method of a coal gasifier and a hot water boiler. [0003] Background technique: [0004] From the 18th century to the present, my country's winter heating has always relied on coal-fired boilers. Although the heating problem has been solved, it has caused great pollution to the ecological environment. By the end of 2012, the total number of existing boilers in the country was 467,000, with a total capacity of 1.78 million steam tons, more than 85% of which were direct coal-fired boilers, which not only consumed a lot of energy, but also emitted soot, sulfur dioxide, and nitrogen oxides every year. They accounted for 33%, 27%, and 9% of the total national emissions respectively. [0005] Coal gasification is a way of clean coal utilization, and coal gasifier gas production tec...
