More particularly, the fire coal that the present invention relates to a kind of optimum organization closes cycle generating system.It is with coal gasification, burning, desulfurization and purification, two power generation cycle of and combustion gas--steam make up in aggregates rightly, form simpler, low in the pollution of the environment and characteristics such as investment and operation and maintenance cost be lower thereby possess generating, power supplying efficiency height, system.
The invention still further relates to a difunctional heat exchanger, have the function of gas cooler and steam superheater.It is to use steam as cooling medium, and coal gas is cooled to below 650 ℃, makes the alkali in the coal gas be frozen into solids full the genus, thereby can make coal gas meet the requirement of gas turbine with ceramic filter with the dust in the coal gas and alkali metal and other particle filterings.Steam is superheated to design temperature to drive the generating of vapor wheel generating set in cooling coal gas.Steam is from the gas-turbine waste heat boiler and the duplexing matter CFBB of native system.So both rationally utilize the sensible heat of coal gas of high temperature, steam superheating can be subjected to the restriction of combustion turbine exhaustion temperature again to very high temperature.
The invention still further relates to a duplexing matter atmosphere circulating fluidized bed boiler.The semicoke that this steam coal gasification furnace produces is made fuel with output high temperature compressed air and these two kinds of working medium of high-pressure saturated steam, utilizes the lime stone calcium oxide (CaO) of coal gasifier remnants simultaneously, further finishes the sweetening process of semicoke.Because the employing of duplexing matter atmosphere circulating fluidized bed boiler makes the gasification furnace in the native system be avoided the poor efficiency stage of coal gasification course, improves its output thereby simplify its structure.Because the heat that coal-char combustion discharges is used for heated compressed air more than 60%, thereby the merit that can improve the combustion machine of combined cycle and steam turbine thermal efficiency of cycle when.
The invention still further relates to a rational sweetening process.In pressurized fluidized bed gasifier, desulphurization reaction can be with the long-pending Shen of the calcium sulfide (CaS) that generates in the flying dust of the semicoke of its close phase layer and coal gas stream.These semicokes and flying dust are admitted to CFBB with residual lime stone calcium oxide (CaO) subsequently, in the fluid bed of boiler, still unreacted sulphur (S) will continue to react with lime stone calcium oxide (CaO) in calcium sulfide (CaS) and the semicoke, and final the generation stablized harmless calcium sulfate (CaSO
4), and discharge with CFBB bed slag.
Known tentatively commercial off-the-shelf integrated gasification combined cycle plants system (IGCC) generally is at high temperature coal all to be gasified as gasifying agent with oxygen.Thereby whole system complexity, own demand are many, investment and operation and maintenance cost height.

Two of purpose of the present invention provides a kind of with the clean combustion of coal association circulating power generation system of air with the coal partial gasification.And its gas cooler and steam superheater are combined, minimizing adds the quantity of steam that water quench coal gas is produced in addition, with the combustion machine of raising system and the merit ratio of steam turbine, thereby improves power plant efficiency.
Three of purpose of the present invention is that the high temperature heat with coal gas makes the saturated vapor of waste heat boiler and binary cycle boiler overheated.Thereby make vapour system may adopt subcritical or supercritical parameter and do not fired the restriction of machine delivery temperature.Also needn't be in waste heat boiler refuelling afterburning in addition, thereby make the waste heat boiler structure single.
Four of purpose of the present invention is the semicokes that come combustion fluidized bed gasification furnace to produce with CFBB.This boiler adopts normal pressure, low range circulation, does not arrange steam superheater.Its furnace wall cooling applies with the abrasionproof fire brick layer, and arranges air heater above burner hearth.Thereby make the major part (more than 60%) of coal-char combustion heat be used to add hot-air.The compressed air that gas turbine can be sent here is heated to about 600～800 ℃ like this, thereby the merit that both can improve the combustion machine of system and steam turbine power plant efficiency when need not to use expensive high temperature heat-resisting again.
Five of purpose of the present invention is the reasonable disposition with system's each several part, tries to achieve the optimum efficiency of whole system.With simple relatively system, simple relatively equipment and structure and lower investment, realize higher generating, power supplying efficiency and less environmental pollution.
