Abstract
The gasifier that provides solid fuel conversion to produce syngas with relevant parameters is the key element of plants generating electric and thermal power, producing chemicals from coal. The purpose of this article is to analyze the modern trends in the development of gasification technologies and determine technical solutions providing the high efficiency of gasifiers and the characteristics of generated syngas that meet the requirements established by the process user. Based on the analysis of the world gasification technologies database, which includes all types of gasifiers in use and gasifiers at the construction or design stage, the data on the development of entrained-flow gasification technologies in the Asia-Pacific (AP) countries are discussed. The major constructional components of gasification plants, fuel-feed and syngas cooling methods and their influence on the efficiency and operational reliability are considered. The analysis of technological solutions confirmed the prospectivity of dry-feed entrained-flow technologies. The staged organization of the gasification process makes it possible to solve issues of increasing the economic and environmental indicators of gasification plant operation. The basic directions of modernization of entrained-flow gasifiers for improving their technical-and-economic perfomance was determined.
