An air distribution duct (12) is connected between the high-pressure air chamber (2) and the lower part of a gas stove (15); the gas produced by the gas stove (15) passes through a gas duct (16), a purification device (18) and a desulfurizer tower (19) and is sent to the mixed combustion room (5) by the high temperature gas supply pipe (3). The utility model directly uses the cheap soft coal as the fuel for the gas turbine machine, successfully connects the gas turbine machine with the gas furnace as a whole for power generation with good effect, thus the operation cost of power generation is greatly reduced.
Description
Affiliated technical field
The utility model belongs to the turbogenerator technical group field, and what relate generally to is the direct-fired coal gas turbine generation of a kind of direct-furnish unit.
Background technique
Known gas turbo-generator set in use has the following disadvantages: 1. the fuel of Shi Yonging is the gaseous fuel of liquid or higher calorific value, and price is higher; 2. air is in pressure process, and gas is in compression process, along with the temperature rising of pressurized gas can make compression efficiency and power all be affected; 3. the normal pressure combustion gas must be compressed directly enters gas turbine after the machine compression and carries out work by combustion, has wasted compression work, and cost of electricity-generating is risen; 4. the high-temp waste gas of discharge of gas turbine generally is to use the waste heat boiler recovered steam, and the grade of utilizing of heat is reduced.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes the direct-fired coal gas turbine generation of a kind of direct-furnish unit, to overcome above-mentioned deficiency.
For achieving the above object, the technological scheme that the utility model is taked is: on the architecture basics of the existing worm gear generator set that is made of gas compressor, high-pressure air chamber, coal gas of high temperature delivery pipe, burner noz(zle), hybrid combustor, multistage worm gear machine and generator, be connected with the air distribution delivery pipe between high-pressure air chamber and gas stove, the coal gas that gas stove produces is sent into hybrid combustor by the coal gas of high temperature delivery pipe through burner noz(zle) through purifier, desulfurizing tower by gas conveying tube.
The utility model reasonable in design because it is directly with the bituminous coal of the cheapness fuel as gas turbine, and successfully is connected as a single entity gas turbine and gas stove and generates electricity, and is respond well, and the operating cost of generating is greatly reduced.The utility model also has following characteristics: 1., pollution-free pollution-free to atmosphere in burning through the coal gas that desulfurization is handled, need not solve environmental issue; 2., coal gas desulfurization is workable than the gas of combustion desulfurization, and can reclaim a large amount of sulphur.3., cost of electricity-generating is low, the steam turbine generator set that uses at present, general efficient is 23.1% (with reference to hydraulic and electric engineering publishing house, " steam turbine equipment and operation " the 14th page " effectively heat energy become the ratio of electric energy be 23.1% "), the highlyest can not break through 28%.And the efficient of gas turbine can reach 43% (with reference to the 201st page of aviation industry publishing house " aero gas turbine engine ").4., investment cost is low, simple to operate, single-machine capacity from 1000 kilowatts to 100,000 kilowatts all organic type can select.
