Abstract
The invention provides an integrated gasification combined power generation device based on pulverized coal air graded pyrolysis gasification. The front end of an entrained circulating bed is equipped with a raw coal pulverizer and a pressurized material conveying system in order, the bottom is provided with a gas distributor and an ash discharge pipe, an entrained flow bed is disposed at a position 300-3000mm above a returning port, and a second stage gas-solid separator is arranged at the top. A heat transfer bin is mounted below the ash discharge pipe, and the bottom is reversely connected to the pressurized material conveying system through a flow regulation valve. The first stage separated coarse ash is connected to the entrained circulating bed returning port, the second stage separated fine ash is connected to the entrained flow bed through a return feeder, and a second stage gas outlet is connected to a high temperature moving bed through a fuel gas heat exchanger. A gas turbine and a first stage gas compressor, a second stage gas compressor and an electric generator are in coaxial type connection linkage in order, one outlet of the first stage gas compressor is communicated with a burner, and the other outlet accesses the second stage gas compressor. A softened water inlet access a steam turbine through a waste heat recovery boiler, the steam turbine is in connection linkage with the electric generator, and the steam turbine and the second stage gas compressor are both communicated with a gas distributor air inlet pipe.
Description
1. Technical field [0001] The invention provides an integrated gasification combined power generation device based on pulverized coal air staged pyrolysis gasification, which belongs to the field of coal chemical industry. 2. Background technology [0002] The common sense in the field of energy is that coal is cheap but highly polluting energy. Therefore, the development of clean coal utilization technology has always been the goal of the joint efforts of governments and industries around the world. [0003] At present, there are two schools of clean coal power generation technology in China. One is to improve the efficiency of conventional coal-fired units. The main method is to increase the temperature of the main steam and enhance the working capacity. It is an independent Rankine cycle, such as supercritical and ultra-supercritical. The other is IGCC (Integrated Gasification Combined Cycle), that is, the integrated gasification combined cycle power generation system, w...
