2019-11-20 · A thermal power station is a power station in which heat energy is converted to electric power.In most places the turbine is steam-driven.Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine the steam is condensed in a condenser and recycled to where it was heated. This is known as a Rankine cycle.
Steam boiler systems typically require saturated steam, which means the water and the steam in the vessel must be at the same temperature. In a low pressure boiler the pressure does not exceed 15 psi and the temperature will not rise above 250 degrees F. Low pressure steam boilers do not need to be monitored regularly and usually only have to

2019-12-7 · Manufacturing processes have improved so that the pump can be located in the boiler discharge water with no adverse effect on the pump. The pump location is determined by where the expansion tank is connected to the system. When the pump is off, the only pressure existing is static pressure (see Info-Tec 26, Hot Water Heating Systems).
For certain pressures, there is a maximum level of contaminants to you can feed into the boiler, and as you increase the pressure in your boiler, it becomes more critical for thorough water treatment that yields higher quality water. Low pressure boilers (600 PSI and lower).
