Functionality of Marine Boilers

If a ship, for instance, is steam powered, two or more boilers will be provided to produce high temperature, high pressure steam. On the other hand, if a ship is powered by a diesel engine as the main propulsion system, then one or two small boilers are used for running various ship’s machinery and services. It is essential to keep boilers running to their full potential to make all the difference to a maritime operation, for a number of different reasons. Always remember, the smoother the boiler’s operation, the more effective it will be in its performance. How Boilers Work? The main job of a boiler is to produce high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure. Inside the boiler, the fuel is burnt in a combustion chamber. Air is supplied to this combustion chamber through a separate arrangement to attain ...

High Flux Tube Heat Exchanger

High Flux Tube Heat Exchanger High flux tube is bare tube evenly coated with a thin layer porous metal with multiple micro pores and interconnected tunnels. Surface porous coat not only increases heat transfer area, but also forms innumerable nucleation site to largely increase nucleation rate. Interconnected pores can also agitate local liquid during bubbling process, further increasing heat transfer coefficient outside tube. With synergy of many enhancements, heat transfer efficiency is greatly improved. Features Compared to bare tube, heat transfer area can be reduced by 27.5%. Equipment operation capacity can be increased by 20%. Total heat transfer coefficient is increased by 89%. Boiling can be achieved by lower temperature difference. The requirement of heat source temperature is decreased with outstanding energy conservation effect. Application Widely used for reboiler, evaporator, condenser and so on when there is phase transition. Tube Specs Diameter: ф12...
