How is oil used in thermal power plant?

Heavy and crude oil transported by ship is stored in specialized tanks, after which it is sprayed into boilers by use of pumps. One liter of heavy oil normally produces approximately 41,000 kJ (10,000 kcal) of heat.

What is emergency oil pump?

Emergency pump. The emergency pump is also mounted on the tank cover and is a submerged centrifugal type which also provides lube pressure under startup or shutdown conditions. This pump is driven by a 125 V 5 hp direct current (DC) flameproof motor.

What is a jockey pump used for?

Jockey pump or pressure maintenance pump is a small apparatus that works in conjuction with a fire pump as part of a fire-protection sprinkler system. It is designed to keep the pressure elevated so that the main fire pump is prevented from running unless absolutely necessary.

What is the capacity of jockey pump in fire fighting system?

About two days ago, my colleague asked me about inconsistency in our design basis of fire fighting system of our on-going project. In our design basis, we stated that the capacity of jockey pump is 50 gpm (the capacity of main fire pump is 500 gpm for electric motor fire fighting and diesel engine fire fighting, respectively).

What types of pumps are used in thermal power plants?

Gathering expertise from all related areas, we provide various types of high-quality, reliable pumps for thermal power plants, including boiler circulating pumps, circulating water pumps and condensate pumps. This is the pump peculiar to the forced circulation type boiler. This pump is necessary for protection of the cooling pipe of the furnace.

How many pumps are used in a power plant?

Pumps and pumping systems are used in power plants for primary applications such as fuel oil handling and for auxiliary systems such as lubrication and cooling (Figure 1). On average, a 300 MW combined cycle power plant will have more than 100 pumps.
