China Smoke Tube Marine Exhaust Gas Boilers

Smoke Tube Marine Exhaust Gas Boiler
1)Heating Surface: 35-250m2
2)Engine Power: 1100-12000KW
3)Working Pressure: 0.7MPa
4)Class: CCS, DNV, ABS, NK, GL, BV, LR, RS, KR, RS
Descrition:
The furnace and smoke side of boiler tubes absorb the heat produced by fired oil and transfer it to water, then the water will be evaporated into steam. Steam rise up and enter the vapor space because its specific gravity is reduced. The space left by steam will be made up by water with a heavier specific gravity. This process forms a natural steam-water circulation. When the water level becomes lower because water is evaporated into steam continuously, the feed water pump will feed water into boiler to keep the water level in the normal range. This process continues and steam will be produced continuously by absorbing the heat produced by fired oil to heat water.
Specifications:
Marine Exhaust Gas Boiler
This series boiler is used for producing steam and hot water by absorbing the exhaust gas heat from diesel engine, as to improve the efficiency of diesel engine. So boilers operator should attach importance to the exhaust gas boilers management and also should familiar with the boilers structure and relevant system, should do the daily maintenance, and make the boilers yield benefit.
Brief instruction to boilers structure
The boiler is a natural circulation vertical exhaust gas boiler with smoke tube. It consists of boiler body, upper & lower smoke chamber; Exhaust gas bypass equipment and so on.
The boiler body is formed the drum by shell, plain end and lower tube plate. Upper tube plate is inside the drum, the upper tube plate is welded with lower tube plate by steel tube, the upper tube plate is connected with plain end by smoke chamber plate. It is the circular steam space outside of the smoke chamber, the flue is in the above of upper tube plate, all smoke tubes are covered by boiler water, smoke box is in the under of lower tube plate, and the smoke box is connected with the exhaust gas bypass equipment. There are many hand-holes under the shell. In view of the convenience for checking & repairing boiler, manhole will be installed on the boiler.
