boiler steam lng 1 lube is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
2013-3-14 · 4. UST boiler 4.1 UST boiler The re-heater is designed to achieve a specified steam temperature by using the reheat burner (Fig. 7Fig. 7). The reheat burner stops automatically in low steam flow con-ditions (reduction of tube cooling effect), so that the tubes are not exposed to high temperature combustion gas. In
If the steam turbine lube system oil is not kept clean and dry, you risk very expensive repairs or replacements, and downtime of the plant. The main problem with the steam turbine lube oil is water ingress due to leakage through the labyrinth seals, but also condensed water in
2019-4-12 · 1. EFFECT OF FUEL TYPE ON BOILER DESIGN Every boiler is designed to burn a particular type of fuel and, conversely, the selected fuel type is an important factor in the design of boilers. The major effects of fuel type on boiler design are the following: - Furnace size - Design, amount and location of heating surfaces (superheater, reheater
original boiler system design, ABS recommends that safety assessments be made for each individual operational case in order to ascertain the feasibility of such an operation. p) The fuel oil systems in LNG ships with steam turbine propulsion are designed for HFO in combination with the boil-off from the cargo.
2016-10-25 · Efficiency in boilers and beyond Steam production and waste heat recovery . 2 In 2007, a new generation of MISSION boilers Producing steam with LNG is no simple task. A EEC module to increase steam production 1. Main engine(s) 2. Auxiliary engine(s) 3. Oil-fired boiler 4. Auxiliary engine waste heat recovery
2018-9-17 · to deliver the feed water to main steam boilers of LNG ships. Coffin main feed water pump is constructed as a two staged centrifugal pump  and Shinko main feed water pump is of three stages centrifugal type pump . Both feed water pumps are driven by the short and light weight Curtis wheel steam turbine [1, 2].
