supercritcal boilers for power plant

You have to know the supercritcal boilers for power plant energy consumption (main steam temperature solve the problem) main steam temperature problem-solving measures 1 boiler operation 1.1AGC control measures to closely monitor fluctuations in the amount of coal, the fuel surge slashed the emergence of the subject Save heated conditioned manual intervention. 1.2 artificially adjusting the load, increase or decrease the amount of coal can not be too large. 1.3 adjusted to optimize the combustion tests, the optimum value of oxygen boiler, the boiler properly regulate the amount of oxygen. 1.4 put into operation the burner adjustment mode, by adjusting ensure that the main steam temperature combustion boiler. 1.5 normal temperature control into the main steam boiler. 1.6 intense monitoring segments superheater steam temperature, steam temperature adjustment for adjusting so that ground, the fine reduced spray desuperheater water, controlling the main steam temperature. 1.7 Test mastered by pulverizing system operation changes the influence of the main steam temperature, analyze the causes and make predictable adjustments. 1.8 rational for sootblowing heating surface. 1.9 stratified fuel amount adjustment, reasonable control center of the flame, adjust a secondary air ratio, the excess air ratio changing, if necessary. 2 routine maintenance and testing 2.1 combustion adjustment experiment to determine the best mode of operation and control parameters boilers. 2.2 improve the quality of automatically adjusting the main steam temperature. 2.3 to detect and analyze the reasons offset the center of the furnace flame occurs, and take specific measures. 3 3.1 eliminate downtime desuperheating water leak phenomenon each valve. 3.2 heating surface power, clean fouling. 3.3 dredge preheater, treatment of flue leakage. 4 4.1 pairs of respective transformation means within the steam separator drum for cleaning up, and remove related defects. 4.2 pairs of waterwall, economizer, reheater, superheater tube cutting, scaling internal corrosion test cases. 4.3 heating surface slagging, fouling cleaning. 4.4 due to equipment problems reheat steam parameters less than the design value, or burner heating surface transformation.

Furnace explosion of the causes of ordinary gas supercritcal boilers for power plant steam boiler gas burned in open flame and furnace process, if the following three conditions appear, it is easy to attack blast furnace accident. 1, open burning furnace, furnace residual gas content limit to reach the fire. 2, open incinerator, several points Eventually, the content of the furnace gas reaches the ignition limit, and then incinerated. 3, halfway flameout, fuel discharge series, spontaneous combustion of the fuel in the furnace temperature can change, so that the gas reaches the ignition limit of the content, and then incinerated. Forming flame halfway reasons are as follows: 1, gas is not supplied in succession. 2, during the adjustment, the valve opening degree increases or decreases suddenly. 3, lean fuel-rich flammability limit narrow. In order to avoid the onset of blasting incidents of burning fuel gas-fired boiler initiative and flame monitoring protection devices should be installed.

Boiler (power generation) - Wikipedia

Supercritical steam generators are frequently used for the production of electric power. They operate at supercritical pressure. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi or 22.06 MPa) that actual boiling ceases to occur, the boiler has no liquid water - steam separation.

Lean and clean: why modern coal-fired power plants are better

Jun 21, 2016 · In ultra-supercritical steam (USC) power plants, the extreme boiler temperature and pressure heat the water so that it becomes a 'supercritical' fluid that exhibits properties of liquid and gas phases. In this state, supercritical steam is much more efficient at driving the giant turbines that spin the plant's generators.
