A new gasification process burner with jet impingement cooling

Abstract

The invention discloses a novel jet impingement cooling gasification technology burner. The novel jet impingement cooling gasification technology burner comprises a central gasifying agent channel, fuel channels, outer gasifying agent channels, and cooling water channels; the central gasifying agent channel is coaxially sieved by the fuel channels and the outer gasifying agent channels successively; the cooling water channels are arranged between the central gasifying agent channel and the fuel channels, between the fuel channels and the outer gasifying agent channels, and on the outsides of the outer gasifying agent channels; the cooling water channels are composed of water inlet channels and water return channels; cooling water uniform distribution devices are arranged in the water inlet channels; the water inlet channels and the water return channels are communicated via a plurality of circular holes which are closely arranged on the lower channel parts of the water inlet channels; high pressure cooling water is delivered into the water inlet channels, and then the walls of the water return channels are impinged by the high pressure cooling water through the plurality of circular holes which are closely arranged on the lower channel parts of the water inlet channels in a jet flow manner, so that high efficient cooling of the walls of the water return channels is realized; and then the high pressure cooling water is delivered to water outlets of the cooling water channels via the water return channels. The novel jet impingement cooling gasification technology burner is capable of solving problems of existing gasification technology burners that cooling effect is poor, and service life is relatively short.

Description

technical field [0001] The invention relates to the field of coal gasification, in particular to a novel jet impingement cooling gasification process burner. technical background [0002] Coal is an important energy source, but for a long time, the use of coal has been accompanied by serious environmental pollution. In recent years, people have paid more and more attention to clean coal technology aimed at reducing pollution emissions and improving utilization efficiency; coal gasification technology, as one of the coal processing and conversion technologies, is considered to be one of the most efficient and clean clean coal technologies. [0003] Coal gasifier is a device that converts fossil fuels (powdered coal, petroleum, natural gas, etc.) into coal gas, and is widely used in chemical industry, nitrogen fertilizer, gas, combined power generation and other fields. In view of our country's poor oil, little gas, and more coal resources, the gasification fuel in my country...
