Problems solved by technology

The traditional coal-fired power generation is to directly send pulverized coal into the coal-fired boiler for combustion. On the one hand, the resource utilization efficiency is low, and on the other hand, a large amount of particulate matter (PM 2.5 and PM 10 ), SO 2 , NO X , CO, etc. need to be managed at the end

Abstract

A coal-to-liquids and gas generating cogeneration apparatus and method are disclosed. The coal-to-liquids and gas generating cogeneration apparatus comprises an integrated apparatus subsystem for extracting coal tar and making gas from coals, a subsystem for preparing cleaning fuel from coal tar, and a subsystem for combusting gas and generating power, wherein the integrated apparatus subsystem for extracting coal tar and making gas from coals comprises a charging unit, a raw coal upgrading conversion unit, and a raw coal upgrading conversion, reaction products separating and purifying unit, the subsystem for preparing cleaning fuel from coal tar comprises a coal tar pretreatment unit, a coal tar hydrogenation unit, and a coal tar hydrogenation products separating and purifying unit, and the subsystem for combusting gas and generating power comprises a steam generation unit and a Rankin-reheating cycle generating unit. The coal-to-liquids and gas generating cogeneration apparatus combines gas generating technology and cleaning fuel preparing technology, and realizes leveled utilization of coal resources, multi-level conversion and high-efficient cleaning conversion and utilization. The raw coal is wide in adaptability, and no secondary pollution is generated. Gas flue is free of lead, chromium, cadmium, arsenic and mercury, and density of NOX and SOX is low.

Description

technical field [0001] The invention relates to the technical field of high-efficiency, clean conversion and utilization of coal and coal-based polygeneration, and specifically relates to a system and method for extracting coal tar from coal to produce clean fuel, and feeding the by-product crude gas into a power plant boiler for direct combustion power generation. Background technique [0002] According to the data released by the National Bureau of Statistics, it is estimated that by February 2015, my country's per capita power generation installed capacity will historically exceed 1kW. At present, my country's total installed capacity of power generation and total power consumption have surpassed that of the United States and ranked first in the world. As of the end of 2014, the installed capacity of power generation in the country reached 1,360,190,000 kilowatts. In terms of power generation structure, my country's thermal power installed capacity accounts for 67.4% of ...
