Cracking and gasifying reforming furnace

Abstract

The present invention discloses one kind of cracking and gasifying reforming furnace, which includes one dust cloud combustor, one cracking and gasifying chamber and one catalytic reforming chamber. Micron level fuel is burnt in the dust cloud combustor to provide heat for cracking and gasifying and catalytic reforming, the material to be cracked and gasified absorbs heat in the cracking and gasifying chamber to crack and gasify, and the cracked and gasified product is pressurized into the catalytic reforming chamber and reformed to obtain medium heat value fuel gas containing CO and H2 in about 80 %. The cracking and gasifying reforming furnace adopts crop stalks and solid forest waste crushed to micron level as outer heat source, has less investment in apparatus, high heat efficiency, low cost, high gas yield and high heat value of fuel gas product, and may be used in utilizing organic garbage to produce fuel gas.

Description

technical field [0001] The invention relates to a pyrolysis gasification reforming furnace, which is suitable for organic matter and coal powder, and is especially suitable for pyrolysis gasification reforming of urban organic garbage and agricultural and forestry waste to produce fuel gas. Background technique [0002] With the depletion of fossil energy and the seriousness of environmental problems, the development of clean renewable energy and the recycling of waste have become urgent issues. [0003] Disposal of municipal solid waste is a major worldwide problem plaguing urban development. However, no matter whether it is landfill, incineration or composting, or other methods derived therefrom, there are defects or deficiencies. For example, the investment in landfill and incineration is huge, the efficiency of resource utilization is extremely low, and secondary pollution is likely to occur at the same time; the added value of waste composting is low, and it is difficu...

AI Technical Summary

Problems solved by technology

[0006] (1) The fixed-bed gasifier intermittently adds raw materials and intermittently produces gas, which affects the use;

[0007] (2) The gasification process and the reforming process are carried out in two different furnace bodies respectively, with complex structure and low heat utilization rate;

[0008] (3) The gasification gas with air as the gasification agent contains a large amount of N 2 and CO 2 , low calorific value of gas;

[0009] (4) The gasification efficiency is low, and a large amount of tar will be produced, which is easy to cause secondary pollution;

[0010] (5) The reformer needs an external heating source. If coal is used, it will easily cause secondary pollution. If electricity, gas or fuel oil is used, the cost will be high
