Fuel gasification combustion equipment and fuel gasification combustion method

Abstract

The invention provides fuel gasification combustion equipment and a fuel gasification combustion method. The fuel gasification combustion equipment comprises a fuel storage tank (1) used for storing a liquid fuel for gasification combustion, a gasifying device used for performing high-temperature gasification and gas-state delivery on the liquid fuel from the fuel storage tank (1), and a combustion device (10) used for combusting the gaseous fuel from the gasifying device. The fuel gasification combustion method comprises the following steps of: delivering the liquid fuel under a certain pressure to the gasifying device, performing high-temperature gasification on the liquid fuel in the gasifying device, and outputting the gaseous fuel resulting from high-temperature gasification under an increased pressure for combustion under a constant pressure or continuously-variable pressure.

Description

technical field [0001] The present invention relates to a fuel oil gasification combustion equipment and a fuel oil gasification combustion method, in particular to a combustion equipment and a combustion method with back pressure and continuous variable pressure adjustment functions which are used in the field of coal chemical industry and use fuel oil as the start-up or working medium . Background technique [0002] In recent years, the coal chemical industry dominated by coal coking, coal gasification-methanol-fertilizer has developed rapidly, and the proposed and newly-built coal chemical projects across the country account for more than half of the total projects. The methanol / synthetic ammonia plant is facing the plight of shortage of raw material sources. On the other hand, for domestic coal chemical enterprises that can use natural gas from their own old plants to implement raw material route transformation, 90% belong to small and medium-sized enterprises with an a...

AI Technical Summary

Problems solved by technology

[0004] Shell company adopts the way of diesel atomization combustion, pre-atomizes diesel oil with oxygen and burns it, with 0-1.0MPaG back pressure load adjustment function, but there are problems such as easy ablation at the end of the burner during use, and the maintenance of the burner requires It takes a lot of money and time to send it abroad through the patent dealer, which seriously affects the efficiency of the device and its long-term stable operation

[0005] Texaco's diesel burners are started at normal pressure, manually ignited, with a low degree of automation, and cannot realize the step-up and load-change regulation of the gasification process
