. PLANT TRAINING REPORT

POWER HOUSE

Power house is one where electric power is produced using fuel. The fuels used

are coal and bagasse. Fuel is fired in a closed vessel called as boiler & stem is producedfrom water in it. This steam is utilized to run the turbine & electric power is produced

from alternator coupled to it.

The whole power plant can be divided in to two sections.

Boiler Section

Turbine Section

There are different systems in power plant as-

Fuel handling system for coal & bagasse.

Syrup from evaporation section is boiled in pan section. The syrup is made to flow

through the pipes & steam is supplied from the shell side. Sugar powder is added as seed.

(acuum is created in pan by condensing the vapor formed in condenser.
