How work FD fan

FORCE DRAUGHT FAN-

The Induced Draft (ID) fans and Forced Draft (FD) fans provide control for draft and forced air zoning of fuel burned furnaces of steam generation plant of a thermal power plant. Forced Draft (FD) fans are used for supplying the combustion air into the furnace of a boiler.

Generally in Thermal power plant Measure There is Three FANS

1. FD FANS- Force draught fan uses for Providing more Oxygen for fuel Combustion in Boiler as proper fuel combustion increase Boiler efficiency.

2. PA FANS- Primary air fan uses for Pushing Pulverized Coal from Coal mill to Boiler Burner end.

3. ID FANS- Induce Draught fan uses for Removing Ash particles and Boiler Exhaust flue gases pulling upto Chimney.

Condensate extraction pump in thermal power plant

WHAT IS CEP (CONDENSATE EXTRACTION PUMP) - This pump is in actual efficiency booster in a thermal power plant. As we all know that very high temperature and pressure steam expands in a steam turbine and this expanded(low pressure and low temp) steam can go waste if CEP doesn't perform it's function. CEP pump circulate the -Condensate(conversion of steam into water in condenser) again into deaerator tank which prevent plant from a huge loss of water. This water can be used for making deaerator level. Condensate Extraction Pump, as the name suggests the CEP is required to extract the condensate from the Condenser. Condenser is the equipment where all the steam gets condensed and the condensate is extracted out of the same by CEPs. so where the Condensate goes after coming out of the condenser, so it goes to the DEAERATOR by moving through a series of LP heaters, where the temperature of the extracted condensate is increased to a certain degree. In deaerator the soluble gases are

Boiler tube

THERMAL POWER PLANT BOILER TUBES A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes , as well as hot gases, enclose the tubes . Not like fire tube boilers , this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. The steam generators of the 660 MW units would be 100% coal fired and would be rated to generate about 2170 t/hr each, of superheated steam at about 250 kg/ cm2 pressure and 568°C temperature. Reheat steam temperature would also be 568°C. Boiler Erection of Water Tubes...... How do I find a leak in my boiler tube? For detecting boiler tube leaks, plant operating engineers constantly monitor boiler furnace vacuum, which is maintained between a -10 to -20 mm water column, feed water flow to the boiler drum from the feed pump, which must not abruptly increase, the de-aerator level, the quantity of makeup water, and hissing sounds What causes boiler tube l
