Abstract

The invention discloses a gasifier baking device capable of automatically adjusting temperature, and belongs to the technical field of coal gasifiers. The gasification furnace baking device capable of automatically adjusting the temperature comprises a gasification furnace and a baking furnace assembly, the gasification furnace comprises a furnace wall, a coal inlet is formed in the top end of the furnace wall, a coal gas outlet is formed in the side face of the top of the furnace wall, and a cooling layer is arranged on the outer side of the bottom of the furnace wall. The oven assembly comprises an oven feeding device, a temperature detection device and an automatic control valve, the oven feeding device is detachably installed in the coal inlet, the automatic control valve is detachably installed at the end, away from the oven wall, of the coal gas outlet, and the temperature detection device is installed on the outer side of the middle of the oven wall; and the temperature detection device is connected with the automatic control valve through a heat-resistant hose. According to the invention, the problems that the internal temperature of the gasification furnace is difficult to keep equivalent and the temperature control precision of the baking furnace is not enough in the baking furnace device on the market at present are effectively solved.

Description

technical field [0001] The invention relates to the technical field of coal gasifiers, and more particularly, to a gasifier oven device for automatically adjusting temperature. Background technique [0002] The purpose of the gasifier oven is to make the furnace wall reach a certain degree of dryness, so as to prevent the furnace wall from cracking due to the dampness of the furnace wall and uneven expansion after sudden heating during boiler operation. In addition, the oven can also make the ash joints of the furnace wall achieve better strength and improve the high temperature resistance of the furnace wall. [0003] At present, there are two main methods of gasifier oven, namely flame oven method and steam oven method. When baking the furnace, the heating curve should be determined according to various boiler models, whether it is a light furnace wall or a heavy furnace wall, the time and local climatic conditions and other factors, and the furnace should be baked accord...
