Method for safe operation of steam combined steam power plant boilers steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Refers to the operation of the steam boiler is refluxed pressure activated device circulating pump, the circulating pump outlet, inlet, outlet, and the system, it is in the normal range. Circulation pump run for 30 minutes. After the stability of the system, the next step. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, if you accidentally quenching phenomenon occurs, the device will automatically interlock burner saver appear. It must be promptly cut off the natural gas pipeline to start the furnace purification. Replacement of the residual gas in the furnace and closed. The system load requirements, temperature requirements and thermal oil outlet, the burner can automatically adjust the size of the fire source.

Gas combined steam power plant boiler precautions required during installation methods, or steps :( a) a foundation base of the boiler should be provided is determined according to the local soil, manufacturers design reference by the civil sector again. After reaching the base strength boiler, the boiler should drawings inspection and acceptance, and to draw the whole boiler three reference lines: a, longitudinal reference line - drum center or the center of the combustion apparatus. b, lateral reference line - the center of the front axle or chain grate slag centerline of the machine. C, elevation reference line - can be selected from a number of locations about four weeks, respectively, on the basis of the marking, the relative offset between the markers should not exceed 1mm. Furnace in place. After assembly the lower part of the boiler in place first, then the upper assembly large, the upper and lower portions need to find a combination of two positive pads firmly, should be both inside and outside the two casting. Installation location and size deviation test methods according to GB50273 "boiler installation engineering construction and acceptance" implementation. (B) lifting the boiler, during lifting, should be suspended on a lifting lug drum boiler ready large, the boiler on a foundation base coincides with the pre-drawn reference line. The longitudinal centerline of the boiler and the foundation, the deviation is not more than 3 mm, and the inclination with the center line of the drum hammer correction, allowing the central drum inclination is not larger than 5 mm, otherwise use horns foundation base and the junction pad level. Maximum level (c) Installation of boiler network (1), water supply conduit installation requirements typically require as backup pool below the normal water level line of the boiler, so as not to shutdown, boiler feedwater flowing into a large number of drainage caused to start the next . At the outlet of the tank (i.e., an inlet feed line) should be installed wire screen. (2), a main steam line installation requires the main steam lead pipe straight run section should be more than 0.5 m, the bending radius should be 4-5 times the diameter of the pipe, the trap should be fitted at the lowest line in order to prevent water hammer pipe, while to be reliable insulation. (3), the safety valve should be installed in the valve installation requirements after the hydrostatic test, the safety valve shall be fitted exhaust pipe, the exhaust pipe of the safety guide outside the boiler house, allowed valving the exhaust pipe. (4), mounting a lower water table level table downcomer must access a safe place, Hancock rotating flexible water table, not leaking, water table must be installed to the lighting device, easy to observe. (5), a pressure gauge mounting means so that when the scale gauge vertical plates, should be painted red gauge scale to show the maximum allowable pressure boiler, rotating flexible plug gauge, not leaking, water flow, pressure gauges insulation prohibited. (Iv) the boiler chimney installation requirements, when lifting the chimney, the chimney should be straight, horizontal direction lead length should not be too long, generally less than 5 meters, the height of the chimney should comply with relevant national standards. To add chimney rain cap, the weight of the chimney should not fall directly on the boiler chimney take over the host. Installation (e) combustion system: 1, according to the combustion system of FIG power line control circuit, a control signal line and the control line is electrically connected, the program should be installed reliable ignition and flame failure protection devices. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine.

Electric utility interest in supercritical pressure steam cycles has revived in the United States after waning in the 1980s. Since supercritical cycles yield higher plant efficiencies than subcritical plants along with a proportional reduction in traditional stack gas pollutants and CO{sub 2} release rates, the interest is to pursue even more advanced steam conditions. The advantages of supercritical (SC) and ultra supercritical (USC) pressure steam conditions have been demonstrated in the high gas temperature, high heat flux environment of large pulverized coal-fired (PC)combined steam power plant boilers.

Heat Recovery Steam Generators for large combined

2015-4-15·Recovery Steam Generators are key components in the combined cycle. Starting from the early 90s, we began developing our proprietary HRSG design for: - Horizontal gas path, natural circulation, cold casing and top supported HRSG. - Vertical gas path and assisted circulation HRSG.

How Power Plant Boiler Works? -

Reheater coils in the flue gas path does the reheating of the returned steam. The reheat steam is at a much lower pressure than the super heated steam but the final reheater temperature is the same as the superheated steam temperature. Reheating to high temperatures improves the output and efficiency of the Power Plant.

Advantages and Disadvantages of Gas and Steam

Start-up of a steam turbine takes a considerable amount of time specially during cold start-ups and requires a long list of steps before it can operate at base load. Therefore, steam turbines cannot be used as peak power plants. The operation of a steam turbine power plant requires more components than that of a simple cycle gas turbine.
