Solid fuel combustion device with fire grate obliquely arranged and combustion method

Abstract

The invention discloses a solid fuel combustion device with a fire grate obliquely arranged. The solid fuel combustion device comprises a furnace body, wherein an upper air inlet is formed in the upper portion or the top of the furnace body, a lower air inlet is formed in the lower portion of the furnace body, and a furnace chamber is formed in the furnace body; a fire outlet is formed in the side of the furnace body, the fire gate is obliquely arranged in the furnace chamber, the upper air inlet and the fire outlet are located in one side of the fire gate, and correspondingly the lower air inlet is located in the other side of the fire gate; the space, located on the fire gate, in the furnace chamber is a solid fuel containing cavity which is divided into a combustion preparing area and a combustion area from top to bottom, the height of the combustion preparing area is larger than 150 mm, the ratio of the largest breadth width of the fire gate to the height of the fire outlet is not larger than 1.5, and the height difference of the solid fuel containing cavity and the fire outlet is not smaller than 150 mm. The invention further discloses a solid fuel clean combustion method. Due to the device and the method, the clean combustion process of solid fuel can be achieved.

Description

technical field [0001] The invention relates to a solid fuel combustion device with a grate inclined, and a solid fuel combustion method using the device, belonging to the technical field of solid fuel combustion. Background technique [0002] At present, smog has become a disastrous weather in many parts of China, which has attracted the attention of the whole society. In 2014, China proposed at the national level the requirements to strictly control the PM2.5 index and prevent smog pollution through "decompression of coal combustion, strict control of vehicles, adjustment of industries, strengthening of management, joint prevention and control, and governance by law". Therefore, haze control and haze prevention has become an important project in China's social and environmental governance. [0003] The formation of smog is the result of the interaction between specific climatic conditions and human activities; with the vigorous development of human economic and social act...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the prior art cannot realize the balanced combustion of volatile matter and fixed carbon in the fuel during the combustion process, especially in the feeding link, so that the clean combustion of the solid fuel cannot be realized, and then ideal combustion theory and balanced combustion technology Propose a clean combustion device for solid fuel that can burn the volatile matter and fixed carbon of the solid fuel in balance
