Product thermal capacity : 1-20 t/h Working pressure : 0.7-2 Mpa Available fuel : Nature gas, coke oven gas, biogas, methanol, liquid propane gas, diesel, heavy oil, light oil, crude oil, etc. Available industries : Heat supplying, chemical, food, textile, printing and dyeing, cigarettes and tobacco, fodder, pharmacy, building materials, brewery, rubber, hospital etc. Introduction:
most efficient steam 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.
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.
Higher AFUE numbers translate to higher furnace efficiency, with AFUE 90 percent and above indicating a high-efficiency system. Finding the Most Efficient Heating System: Boilers. The third most efficient heating systems for homes are residential boilers. Boilers are less common in residential settings than heat pumps or furnaces.
Why boilers are so efficient: Condensing boilers use a secondary heat exchanger to take better advantage of the heat created. Most efficient: Condensing boilers have AFUE ratings of 90% to 98%, about equal to gas furnaces. This list of Energy Star Most Efficient boilers includes brands and models.
The Most Efficient Cast-Iron Steam Boiler in the World! The MegaSteam is a U.S. Boiler exclusive. Designed specifically as a residential oil-fired steam boiler, the MegaSteam achieves 86% AFUE efficiency with a 3-pass cast iron heat exchanger – the only one of its kind in the world.
Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high-efficiency versions of all types of furnaces and boilers are currently available.

What’s the most efficient boiler fuel? A gas boiler is most often the cheapest heating solution, but they don’t necessarily save the most over time. If you were to replace an electric heating system with a wood burning system you could save up to £630 a year.
High Efficiency vs. Standard Boilers Replacement. High efficiency boilers generally cost more to install than standard boilers for the following reasons: Initial cost of high efficiency boiler unit is higher. Retrofitting a house to handle a high efficiency boiler may cost extra. Repair and installation of high efficiency boilers may be more ...
The ENERGY STAR Most Efficient 2019 designation recognizes the most efficient products among those that are ENERGY STAR certified. These exceptional gas and oil boilers represent the leading edge in energy efficient products this year. Access the full list of products recognized as ENERGY STAR Most Efficient in Excel.
Most new boilers are equipped with electronic ignition, and although these systems are much more efficient, they are also more complicated. Natural draft vs fan controlled combustion air Natural draft boilers have a specific burner assembly that naturally moves the combustion air upward without a fan.
most efficient steam boiler the most efficient boiler is one which has been properly installed by someone who can read the manufacturer's instruction manual. some boilers are a bit more efficient than others, but in general it is the proper installation, and piping which is most important.--nbc
