Background technology:
Combined cycle generation system of fuel gas-steam is to utilize the mixed gas of low-calorie smelting by-product product to act as a fuel, therefore, stability requirement to the flow of mixed gas, temperature and pressure is very high, in the prior art, be to realize control to coal gas stability by the outlet of control gas compression pump, burning machine inlet place gas pressure control and regulation coal gas diffusion amount.The existing weak point of this method is, because mixed gas comes out to have HTHP from gas compression pump, this operates under HTHP the flow control valve in the coal gas diffusion device, and potential safety hazard is very big, and the precision of control is also poor, can not satisfy the requirement of combustion machine to coal gas.
Summary of the invention:
Purpose of the present invention, be exactly at the existing in prior technology deficiency, and provide a kind of coal gas diffusion method and apparatus technical scheme of combined cycle generation system of fuel gas-steam, this scheme adopts the coal gas diffusion point is placed on the gas inlet pipe road, and making the anti-surge valve increase flow regulating function, the pressure sensor on the pressurized gas output pipe goes to control the flow control valve on the coal gas diffusion pipeline and the flow-control of anti-surge valve by the control computer.So both made full use of the function of anti-surge valve on three times one return lines, and made the flow control valve on the coal gas diffusion pipeline avoid under high temperature, high pressure, moving again, and guaranteed the safe operation of equipment, and improved control accuracy.
This programme is realized by following technical measures.
The coal gas diffusion method of the combined cycle generation system of fuel gas-steam of this programme, this method includes the gas compression pump that is connected with the gas inlet pipe road, pressurized gas output pipe that gas compression pump is connected with the combustion machine and the pressure sensor on the pressurized gas output pipe, and the cooler and the anti-surge valve that on three times one return lines between gas inlet pipe road and the pressurized gas output pipe, connect, also be useful on diffusing flow control valve and diffusing tower apparatus on the coal gas diffusion pipeline of coal gas diffusion and the coal gas diffusion pipeline, the characteristics of this programme are that described coal gas diffusion pipeline is to be connected with gas inlet pipe road before the gas compression pump, and the increase of described anti-surge valve has flow regulating function; Pressure sensor on the described pressurized gas output pipe is by the Flow-rate adjustment of control computer control anti-surge valve and the Flow-rate adjustment of diffusing flow control valve.
The employed equipment of coal gas diffusion method of the combined cycle generation system of fuel gas-steam of this programme, this equipment includes the gas compression pump that is connected with the gas inlet pipe road, pressurized gas output pipe that gas compression pump is connected with the combustion machine and the pressure sensor on the pressurized gas output pipe, and the cooler and the anti-surge valve that on three times one return lines between gas inlet pipe road and the pressurized gas output pipe, connect, also be useful on diffusing flow control valve and diffusing tower apparatus on the coal gas diffusion pipeline of coal gas diffusion and the coal gas diffusion pipeline, the characteristics of this programme are that described coal gas diffusion pipeline is to be connected on the gas inlet pipe road or to be connected on three times one return lines of gas inlet pipe terminal, and described anti-surge valve is the anti-surge valve with flow regulating function.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, the coal gas diffusion point is placed on the gas inlet pipe road, and the anti-surge valve has been increased have flow regulating function, the pressure sensor on the pressurized gas output pipe goes to control the flow control valve on the coal gas diffusion pipeline and the flow-control of anti-surge valve by the control computer.The characteristic of three times one return lines and the function of anti-surge valve had so both been made full use of, flow control valve on the coal gas diffusion pipeline is moved under low-temp low-pressure, this has just guaranteed the safe operation of equipment, and has improved control accuracy, has satisfied the requirement of combustion machine to mixed gas stability.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, its implementation result also is conspicuous.
