Sep 14, 2016 · A schematic diagram of a steam power plant is shown in figure 1. In a simple steam power plant, at the top of the boiler high-pressure superheated steam leaves the steam drum, also referred to as a steam generator and enters the turbine. In the turbine, steam expands and in doing so does work, which enables the turbine to drive the electric
A steam power station basically works on the Rankine cycle.Steam is produced in the boiler by utilising the heat of coal combustion.The steam is then expanded in the prime mover (i.e.., steam turbine) and is condensed in a condenser to be fed into the boiler again.The steam turbine drives the alternator which converts mechanical energy of the turbine into electrical energy.This type of power
A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam.
Power plant safety: a wise business move Going to work in a controlled and safe environment is not an unreasonable expectation for any worker. In many occupations, a level of danger is expected because it is inherent to the job, but this is only more reason for companies to take employee safety seriously.
A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam.
Boiler Safety. Workers that use, maintain, and service boilers know that they can be potentially dangerous. Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam.
