WNS series horizontal internal combustion boiler 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.
1. 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.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. 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.
4. 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.
These systems have ranged from modifying the RTR model to all stainless for condensing natural gas combustion below 150°F to preheating boiler feedwater from bio/landfill fired boiler exhaust. Impossible to some, but for one of the largest hospitals in Manhattan we designed and manufactured a large customized RTR unit (lower-left photo) that
Gas-Fired Furnaces and Boilers (includes units fired with natural gas and propane) Oil-Fired Furnaces and Boilers . Other retrofitting options that can improve a system's energy efficiency include installing programmable thermostats , upgrading ductwork in forced-air systems, and adding zone control for hot-water systems, an option discussed in
Rheem's Prestige High Efficiency Natural Gas Combi Boiler Rheem's Prestige High Efficiency Natural Gas Combi Boiler provides an efficient, continuous supply of domestic hot water used for faucets, showers, washing machines, etc.) and provides hydronic space heating for residential applications such radiant floors, baseboards, hydronic air handlers, etc.
The most common system for preheating the boiler feed-water includes a heat exchanger and an auxiliary stream with relatively high thermal content which will transfer energy to the boiler feed-water. The type of heat-exchanger can differ according to the size and water needs of the boiling system, but careful considerations should be taken for

Dec 09, 2015· Exhaust gas boiler (EGB or EGE) or economiser described in this article is a smoke tube boiler with steam space, used for heat recovery from main engine exhaust gas. An illustration of the boiler is shown in figure below. The exhaust gas boiler is designed as a vertical boiler with a cylindrical shell surrounding the boiler tubes and water drum
Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.
Boiler - Fundamentals Steam production and steam uses Multiple gas paths - 2, 3 and 4 pass Internal furnace or fire box as the 1st pass Water tube boiler Multiple drum system low pressure (LP) medium pressure (MP) high pressure (HP) Multi Pressure Boiler System
The present disclosure relates to a boiler water supply preheater system which preheats water (boiler water supply) supplied to a boiler by a predetermined preheating means, wherein the preheating means is a Rankine cycle (thermal cycle) which moves heat of a waste heat source in the boiler to the boiler water supply to perform preheating and drives a generator to generate electric power using
