Boiler (Steam Generator)
Boiler (Steam Generator)
-The boiler for 1,094 t/h MCR is Single Drum Radiant Natural Circulation Boiler “ELPASO” Type which has self-drainable heating surface. The unit is of pressurized furnace design with two regenerative air heaters, two forced draught fans and two flue gas recirculation fans. The boiler consists of the following equipment.
Steam drum
Water wall
Primary Superheater, Secondary Superheater and Tertiary Superheater
Reheater
Attemperators
Economizer
Two forced draft fans
Two gas recirculation fans
Two regenerative air heaters
Two steam coil air heaters
Ducts and flues
Gas and oil burner system
Steel structure
Piping and valves
Other auxiliary equipments
-The boiler and its auxiliaries are designed suitable for firing Natural Gas and back-up Mazout and for the following conditions:-
Economizer inlet to drum inlet : 203 bar(g)
Water wall : 204 bar(g)
Drum and superheater : 201 bar(g)
Reheater : 47 bar(g)
Superheater outlet : 541 °C 181.1 bar(g)
Economizer inlet : 275.8 °C 194.9 bar(g)
Reheater outlet : 541 °C 37.6 bar(g)
Reheater inlet : 328.6 °C 38.9 bar(g)
-Superheater outlet steam Temperature is controlled to constant within the load range from 50% turbine to 100%BMCR by spray attemperation.
-The reheater outlet temperature is controlled to constant within the load range from 50% turbine to 100% BMCR by flue gas recirculation. The reheater spray attemperation for reheat control is used only as an emergency measure during periods of load changes or of low feedwater temperature due to heater outage, or at overloads.
-The main specifications of the boiler are:-
Type of boiler Babcock - Hitachi
Single Drum, Radiant, Natural Circulation Boiler
Evaporation (BMCR) : 1,094.4 t/h
Steam Pressure at SH outlet : 181.1 bar(g)
Steam Temperature at SH outlet : 541 °C
Feed water Temperature : 275.8 °C
Reheat Steam Flow : 941.4 t/h
Steam Pressure at RH outlet : 37.6 bar(g)
Steam Temperature at RH outlet : 541 °C
Steam Temperature at RH inlet : 328.6 °C
Ambient Air Temperature : 34.8 °C
Draught system : Forced draught
Fuel : N.Gas, Mazout Oil
That was a small description of the boiler from (HITACHI BABCOK Company.), Used at Thermal Power Station, the next Post I will talk about each system of the Boiler.
