9.Steam from the steam drum is sent to the primary super-heater.
10.Steam is super heated to a high temperature and pressure in the primary super-heaters and then moves to the secondary super-heaters.
11.In the secondary super-heaters steam meets the very hot gases exiting the top of the boiler. The steam is heated to its final temperature and pressure before leaving the boiler as main steam. The main steam is sent to the high pressure steam turbine. The steam turbines drive a generator which produces electricity.
12.Steam exiting the high pressure steam turbine is called cold reheat. It is reheated in the re-heater and sent back to the second steam turbine. By the time the flue gas exits the boiler most of the energy in the coal will be transferred to the water in the boiler. The hot gases are cleaned up before they are sent to a stack. Feed-water is generally supplied by condensed steam from the low pressure steam turbine. Large amounts of cooling water are used to condense this steam into liquid water in the condenser.
As the cost of powering this equipment by burning fossil fuels has steadily risen, the use of biofuel co-generation as a source of power production has become more prevalent. Many sugar mills have updated their bagasse fired boilers and linked them to generators that produce electricity used to power the mill’s operations and to be sold to the local power grid.
Fast boiler is a very trustworthy business, whether it is the beginning of cooperation or boiler put into operation, such as a party soon have maintained cooperative attitude, patience, careful. To ensure long-term stability of the latter part of the boiler operation, fast boiler technician fireman's gave us a free people to do the training, precautions and reduce the accident rate method full guidance boiler operation. --customer feedback
30 MW coal fired power plant boiler working principle
30 MW Coal-fired power plant boilerproduce electricity by burning coal in a boiler to heat water to produce steam. The steam, at tremendous pressure, flows into a turbine, which spins a generator to produce electricity. The steam is cooled, condensed back into water, and returned to the boiler to start the process over.
