Hundreds of tons of ash may be burnt a day in a power station. Gas Cooled Reactor 53 These boilers often use orifice, which control which control flow circulation. In plant handling includes equipment such as belt conveyer, screw conveyer, bucket elevator etc.
Power Plant Engineering by PK Nag pdf free Download
Weighing and measuring 1. The cooling is assisted in tower with power plant engineering nag pdf download help of two ID fans or a large hyperbolic natural draught tower also be used, depending upon the cooling requirements. The pump pressure is always higher about 2 bar more the boiler pressure in operation. Please enter your name here. In these boilers water enters bottom of the tubes and completely transforms into steam as it pass through tubes and reaches the top.
Please enter your comment! There are two types of indirect dry cooling towers.
General Structure of Nuclear power plant 46 Fuel is admitted to the remaining cylinders and ignited in the normal way causing the engine to start. The fan blade wear is power plant engineering nag pdf download in induced draught system as the blades come in contact with hot gases.
Advantages of Mechanical Draught over Natural Draught: Ash handling 3 3. This nay use of the flues discharged from the furnace and from the economizer.
power plant engineering nag pdf download Advantages and disadvantages of the gas turbine plant, Open and closed cycle turbine plants with the accessories. Economizer and pre heater cannot be used to recover heat from the flue gases. The first one is a direct contact spray type steam condenser, where the turbine exhaust steam is condensed using cooling water.

Pneumatic weighers use pneumatic transmitted weigh heads and corresponding air pressure to determine load applied. Indirect dry cooling tower with a conventional surface condenser Page 22 are connected to the steam header, through which the steam is passed The steam tubes are provided with external fins, so power plant engineering nag pdf download to increase the heat transfer rate and ndenses as water in the condensate headers, and is collected in a condensate Indirect dry cooling tower with a conventional surface condenser The deposition reduced the heat transfer and ultimately the generating capacity.
How to download power plant engineering p k nag file to my device? Hydroelectric Power Plant Chapter The rate of air flow, hence the combustion can be controlled by changing the draught pressures through the ught system does not depend on the environmental temperature.

It can also be used for air heating where the exhaust pipe is surrounded by the cold air jacket. Environmental Degradation and use of Renewable Energy.
Loss in transport is minimized. The commonly used ash handling equipments are, i Bucket elevator. This is a method in which a thermostat maintains the desired temperature power plant engineering nag pdf download protects ppdf engine from getting overcooled. When the coal is delivered in the big form of lumps and it is of not proper size, the preparation sizing of coal is achieved by using crushers, breaker and magnetic separator.

The exhaust pipe should have flexible tubing system to take up the effects plan expansion due to high temperature and also isolate the exhaust system from the engine vibration.
However, the natural draught is highly dependent on the environmental temperature.
It is caused by the density difference between atmospheric air and hot gas in the stack. Just paste the urls downlowd find below and we’ll download file for you!
Notify me of new posts by email. The action of induced draught is similar to the action of natural draught chimney, but the draught heat can be recovered in the air pre heater and economizer, and comparatively Make up water is added periodically to the engineerkng. Flow Duration Power plant engineering nag pdf download 43 Air cooling is used in small engines, where fins are provided to increase heat transfer surf area. It is costly due to increased requirement for steel for heat transfer surface, pump and feed Generation of steam using forced circulation, high and supercritical pressure High pressure boilers can be further classified into 1.
