Embodiment Construction

[0015] The present invention will be further described below in conjunction with example and accompanying drawing.

[0016] like figure 1 As shown, based on the above-mentioned status quo, the present invention proposes a device and method capable of regulating and controlling the combustion temperature of porous solid fuel and increasing the heat exchange efficiency after combustion. The gas return channel, the combustion zone is set in the furnace body, the heat exchange area is set in the pot body, the high-efficiency heat exchange device is set in the heat exchange area, the flue gas return hood and the flue gas return control device are set on the flue gas return channel, and the specific control methods are as follows:

[0017] a. The flue gas return hood on the flue gas return channel and the flue gas return control device lead out part of the flue gas and air from the flue before entering the combustion area in the furnace body or outside the furnace, and then enter th...

Abstract

The invention discloses a device and method for regulating and controlling combustion temperature of porous solid fuel and increasing heat exchange efficiency after combustion. The device and the method are characterized in that the device comprises a furnace body, a boiler body, a flue and a flue gas backflow channel, a combustion area is arranged in the furnace body, a heat exchange area is arranged in the boiler body, an efficient heat exchange device is arranged in the heat exchange area, and a flue gas backflow cover and a flue gas backflow regulating and controlling device are arranged on the flue gas backflow channel; and the method comprises the specific regulating and controlling steps that a, the flue gas backflow cover and the flue gas backflow regulating and controlling devicelead out part of flue gas from the flue to be sufficiently premixed with air inside or outside the furnace body before entering the combustion area and then enters the combustion area of the furnace body, the oxygen concentration in the combustion area in the furnace body is regulate and controlled, and the combustion temperature of the porous solid fuel is regulated and controlled; b. the efficient heat exchange device in the boiler body can enhance the heat exchange efficiency of the heat exchange area and control the flue gas temperature at the outlet of the flue; and c. porous solid fuel is produced by a retorting process.

Description

Technical field: [0001] The patent of the invention belongs to the field of fuel controlled combustion, and specifically relates to a device and method for regulating the combustion temperature of porous solid fuel and increasing the heat exchange efficiency after combustion. Background technique: [0002] Combustion is still the main way for humans to obtain energy, and the combustion of various fuels has brought many adverse effects on the environment (such as emitting a large amount of greenhouse gases, nitrogen oxides, sulfides, etc.). Although my country's combustion technology and equipment have made great progress in the past ten years, there are still problems of high energy consumption, low energy efficiency, ineffective treatment of "three wastes", and serious pollution, especially the combustion pollution of civil loose coal in my country. Invention content: [0003] Based on the above present situation, the present invention proposes a device and method capab...
