How many fire tubes are in a Lancashire boiler?
Construction of Lancashire Boiler This boiler is similar to a shell and tube-type heat exchanger. It consists of a large drum of diameter up to 4-6 meters and length up to 9-10 meters. This drum consists of two fire tubes of a diameter up to 40% of the diameter of the shell.
What is the function of fusible plug in the boiler?
The function of fusible plug is to protect the boiler from damage due to overheating of boiler tubes by low water level. it is simply a hollow gun metal plug screwed into the fire box crown.
What is the maximum efficiency of the Lancashire boiler?
The maximum working pressure in a Lancashire boiler is 16 bar. It is used where working pressure and power required are moderate. Its steam production rate is 9000 kg/hr. Its efficiency is from 50% to 70% depending upon the type of fuel used.
Is Lancashire boiler is a externally fired boiler?
Lancashire boiler is a fire tube boiler whereas Cornish boiler is a water tube boiler. Lancashire boiler has two flue tubes and the Cornish boiler has one fiue tube. Lancashire is horizontal and Cornish boiler is vertical in placement. Lancashire boiler is externally fired and the Cornish boiler is internally fired.
What are the parts of a levellancashire boiler?
Lancashire Boiler also consists of other necessary mountings and accessories. Those are economizer, safety valve, superheater, water gauge, pressure gauge, and some other parts. All are for the better performance of this boiler.
What is a light Lancashire boiler?
Lancashire is a horizontal, stationary fire tube boiler. This boiler is invented by Sir William Fairbairn in the year 1844.The flue gases flows through the fire tube, situated inside the boiler shell, so it is a fire tube boiler. This boiler generatenlow pressure steam.
What is a shell and tube boiler?
Lancashire boiler is a shell and tube type, heat exchanger. The fuel is burned at the grate. The water is pumped into the shell through the economiser which increases the temperature of the water.
What is an internal fire tube boiler?
Lancashire Boiler is an internal fire tube boiler and similar to the cornish boiler in which the flue gases are in the tube and water is surrounding them. As the temperature is maximum so the water gets converted into steam and that steam used at several places for different operations.
