Dust cloud combustion furnace

Abstract

This invention discloses a firing furnace of dust clouds, the middle inner wall of the furnace body is spiral, in the middle of the furnace hearth is the heat accumulator, at the top of the wall of the furnace body is the anti-dust board, on the wall of the furnace body and between the heat accumulator and the anti-dust board are the dust clouds inlet, the diesel oil firing inlet and the primary intake air port, the gasifying furnace chamber is between the hear accumulator and the anti-dust board; the bottom of the furnace is cone-shaped, and the end of the cone is a dust outlet, on the wall of the furnace body and at the bottom of the heat accumulator are the secondary intake air port, the steam inlet, and form the secondary gasifying chamber; the third intake air port is on the wall of the furnace body and the top of the anti-dust board, and form the residual gas burning chamber between the anti-dust board and the top of the furnace body. This furnace can fully fire the plant dust, the efficiency of the burning reaches more than 93%, the temperature more than 1200 deg. C. The heat energy of the burning can use in furnace, the gas turbine, the electricity generating, the heat and cool supply, and etc. It provides the new type technological apparatus for the raw materials utilization.

Description

technical field [0001] The invention relates to a combustion furnace for plant powder dust cloud combustion. Background technique [0002] With the depletion of fossil energy and the seriousness of environmental problems, the development of clean and renewable energy has become an urgent issue. In this context, biomass energy, as a renewable energy that can be stored and transported, has attracted increasing attention from all over the world for its efficient conversion and clean utilization. [0003] Biomass is organic matter produced by plants through photosynthesis. Compared with coal, it has high volatile components, high carbon activity, low sulfur content and ash content. At the same time, in the process of biomass utilization, SO 2 , NOx emissions are small, from the perspective of carbon ecological cycle, CO 2 emissions are zero. Therefore, extensive use of biomass resources saves fossil fuel resources on the one hand, and reduces CO2 on the other hand. 2 , SO ...
