Circulating fluidized bed heat-power-gas-tar multi-joint-production apparatus and method

Abstract

The invention discloses a circulating fluid-bed heat-electric-gas-tar connection device and the method. The device combines the circulating fluid-bed burning furnace and the retort furnace to produce the heat-electric-gas-tar in a suit of system. The device is made up of the fluid-bed retort furnace, the circulating fluid-bed burning furnace, the high temperature separator and the material return which connected the two furnaces, the corresponding appurtenance. So the every components of coal can be used fully by the device; the tar productive rate is high and the calm value of the coal gas is high, the CO content is low by using the circulating fluid-bed solid heating carrier and the warm retort technology. Also it doesn't need the special O2 making device and the CO transforming process, so it has the simple process and the low cost comparing to the gas furnace and the retort furnace.

Description

technical field [0001] The invention relates to a combustion device, in particular to a circulating fluidized bed thermoelectric tar polygeneration device and a method thereof. Background technique [0002] my country has long used coal as the main energy resource, but my country's coal utilization has been in an unreasonable industrial layout that only develops coal production and does not pay attention to the comprehensive utilization of coal. The technology, equipment and facilities of the electric power, chemical and other industries are insufficient and The unreasonable product structure has caused my country's energy consumption per unit of output to be 3-4 times that of developed countries. The development, processing and utilization of coal has become the main source of my country's environmental pollutant emissions, making my country's environment a typical soot-type pollution. [0003] Coal polygeneration system starts from the point of view that coal is also a reso...
