minster and Beevor Boiler

1. Large Thermal Storage
Large water content in boiler to maintain constant pressure of boiler. Large  steam / water  surface to give low escape velocity & hence to ensure drier steam.

2. Lower Tube Metal Temperature
The completely water-cooled combustion chamber increase the proportion of radiant heating surface, lowering the gas temperature into the convection tubes and increasing boiler's overall fuel to steam efficiency. Combustion chamber acts as primary heating surface as well.

3. Concentric furnace designed. Better hot water circulation

4. Accessibility
Boilers are fitted with a 420 mm X 320 mm manhole welded into the top of the top of the shell and two head-holes in the bottom of the shell where access is possible.

5. Less sensitive to poor feed water quality
Research and tests shown that due to lower metal temperature the boiler is more suitable for use with feed-water of poorer quality.

6. Minimum refractory at Burner quarl hence reduces incidence of refractory works.


7. Third pass plain tubes fully expanded
Second pass plain tubes expanded at one end & welded at combustion chamber end with "J" prep.

8. Quality & proven burner is employed to do the duty.
It is "user friendly" and easy for maintenance.

9. Water level controls and alarms are fitted as follow:-
Dual control arranged to cut out the burner and give alarm at first low water level and also to control the feed water pump.

Single control arranged to lockout the burner and alarm at second low water level.
