Embodiment 1

[0053] A set of dry coal powder pressurized gasification reactor with partial waste heat recovery device for processing 3,000 tons of coal per day. The inner diameter of the gasification reaction chamber shell (that is, the water wall 21 of the furnace liner) is 3230 mm, and the inner diameter of the slag discharge port is 25 mm. 1100mm. A layer of four side burner chambers 16 is evenly arranged on the upper side of the gasification furnace. The plane of the side burners is perpendicular to the gasification reaction chamber, the axis is perpendicular, and the radial deflection angle is 4.0°. Enter 100% pulverized coal, 100% water vapor and 100% pure oxygen, and the top burner chamber 17 is used as an ignition / start-up oven burner.

[0054] The cylinder diameter of the chilling conversion chamber 2 is 4150mm. There is one layer of chilling ring 12, and 88 chilling nozzles 13 are evenly arranged along the chilling ring 12 to spray atomized water vapor at 170°C. The nozzle 13 ha...

Abstract

The invention discloses a gasification reactor with a partial heat recovery device and a gasification method by using the gasification reactor. The gasification reactor is characterized by comprising a gasification furnace body and a convection waste kettle, wherein the inside of the gasification furnace body is sequentially provided with a gasification reaction chamber, a shock cooling conversion chamber and a cooling deslagging chamber from top to bottom; the gasification reaction chamber, shock cooling conversion chamber and washing deslagging chamber of the gasification furnace body are arranged coaxially; a top burner chamber and a side burner chamber are arranged on the top in the gasification furnace body; the side of the cooling deslagging chamber communicates with the convection waste kettle through a guide tube section; and the inside of the convection waste kettle is sequentially provided with a reverse chamber, a superheater, a convection waste kettle and a synthetic gas outlet from top to bottom. The gasification reactor and gasification method have the characteristics of stable and reliable operation, environment friendliness, energy saving and the like, and can easily implement large-size amplification.

Description

technical field [0001] The invention relates to a gasification reactor with a partial waste heat recovery device and a gasification method thereof, belonging to the technical field of energy clean utilization. Background technique [0002] The gasification process is the only way to convert solid fossil fuels into gaseous combustibles. The gasification process can be divided into high-temperature gasification, medium-high temperature gasification, and medium-low temperature pyrolysis gasification according to different gasification temperatures. High-temperature gasification is widely used because of its fast reaction speed, high efficiency and environmental friendliness. The mainstream technology of high temperature gasification is entrained bed gasification technology. In the past 20 years, entrained bed gasification technology has been popularized and applied on a large scale. With the continuous upgrading and industrial demonstration and application of various entraine...
