Abstract

The coal powder pressurized gasifying and chilling apparatus includes five parts for coal powder pressurizing gasification, water spraying chilling, chilling in a chilling chamber, clinker exhaustion and grey water treatment separately. The coal powder pressurized gasifying and chilling process includes the pressurized gasifying of coal powder n the pressurized gasifying furnace through reaction with O2 and water vapor to produce crude gas with CO and H2 as main components, chilling of the crude gas in the sparger, further chilling in the chilling chamber, and final washing in the washing tower. The produced synthesized gas may be used in producing methanol, synthetic ammonia, hydrogen, synthetic oil and other chemical product and energy source product.

Description

technical field [0001] The invention relates to a gasification chilling device and a chilling process, in particular to a dry coal powder pressurized gasification chilling device and a chilling process. Background technique [0002] Coal gasification technology, as a leading technology for coal deep processing and transformation, is the key to clean coal technology and a "leading" technology with a wide range of applications. With a development history of more than 180 years, especially the demonstration and commercial operation of large-capacity IGCC power plants in the past 10 years have proved that compared with fixed beds and fluidized beds, entrained beds have better adaptability to coal types and particle sizes and better Technical performance, it is the preferred technology for coal-based large-capacity, high-efficiency, clean, and reliable operation of gas and synthesis gas preparation devices. [0003] The common characteristics of modern entrained bed gasification...
