Problems solved by technology

[0002] The volatile matter decomposed from coal during heating itself is a poor thermal conductor. In the current chain furnace or hand-fired furnace, due to the large negative pressure in the furnace, the flow rate of the volatile matter in the furnace is relatively fast. Although the temperature of the furnace is high, it is still difficult to heat the carbon molecules that form black smoke in the volatile matter to the temperature that reacts with oxygen, thus forming a large amount of smoke pollution

Embodiment 1

[0011] Embodiment 1 The carbon molecules that form black smoke in the volatile matter reach the temperature of reacting with oxygen, so that the carbon molecules in the black smoke are completely burned

[0012] (1) First, the canned gas external heating source is sprayed into the high-temperature combustion zone 4 in the furnace through the flame nozzle 3, so that the temperature of the high-temperature combustion zone is rapidly raised to 800 ° C; (2) The raw coal in the hopper is passed through the feeding device 8 Into the high-temperature combustion zone 4 of the furnace, the coal is burned from the surface layer to the deep part under the high temperature of the high-temperature combustion zone 4, and the air is supplied to the furnace through the air chamber 7. Under the condition of low pressure, the carbon molecules forming black smoke in the volatile matter reach the temperature of reacting with oxygen, so that the carbon molecules in the black smoke are completely bu...

Embodiment 2

[0014] (1) First, the external heating source of the canned diesel is sprayed into the high-temperature combustion zone 4 in the furnace through the flame nozzle 3, so that the temperature of the high-temperature combustion zone is rapidly raised to 1200 °C; (2) The raw coal in the hopper is passed through the reciprocating The feeding device 8 composed of the grate is sent into the high-temperature combustion zone 4 of the furnace, so that the coal is burned from the surface layer to the deep part under the high temperature of the high-temperature combustion zone 4, and the air is sent to the furnace through the air chamber 7, and the combustible coal decomposed Under the conditions of high temperature and low negative pressure, the carbon molecules forming black smoke in the volatile matter reach the temperature of reacting with oxygen, so that the carbon molecules in the black smoke are completely burned; (3) decompose the flammable volatile matter The red-hot coke moves for...

Embodiment 3

[0016] When the temperature of the high-temperature combustion zone is raised to 1000°C, the invention can also be used for the pollution-free treatment of various combustible garbage.

Abstract

The present invention discloses one kind of coal pyrolysing and gasifying combustion apparatus and method. The hearth has one high temperature burning area formed with partitions in one side, flame nozzle for outer heat source and temperature measuring device for measuring the temperature in the high temperature burning area. The coal pyrolysing and gasifying combustion method includes heating the high temperature burning area fast to 800-1200 deg.c with the outer heat source via the flame nozzle and feeding coal into the area for burning from the surface layer to inside; blowing air into the hearth via the air chamber to decompose coal at temperature of 800-1200 deg.c before burning in the complete burning chamber; burning the formed coke in the complete burning chamber; and closing the flame nozzle after the coal burning temperature reaches 800-1200 deg.c to further burn by the high temperature generated in burning coal.

Description

technical field [0001] The invention relates to a combustion device and method, more specifically to a coal pyrolysis gasification combustion device and method, which are suitable for clean combustion of coal. Background technique [0002] The volatile matter decomposed from coal during heating itself is a poor thermal conductor. In the current chain furnace or hand-fired furnace, due to the large negative pressure in the furnace, the flow rate of the volatile matter in the furnace is relatively fast. Although the temperature of the furnace is high, it is still difficult to heat the carbon molecules that form black smoke in the volatile matter to the temperature that reacts with oxygen, thus forming a large amount of smoke pollution. The condition for full combustion of coal is to heat every carbon molecule on the polymer skeleton to 800-1200°C, and then it can react with oxygen to realize gasification and combustion. Therefore, ensuring that each carbon molecule has a high...
