High Efficiency Gas Boilers Heat Exchanger 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.

HSE125 and HSE145 are condensing boilers that do more for less. Among the most versatile heating appliances on the market, they combine domestic hot water and central heating in a single compact unit. HSE is the Heating, Smart, Efficient solution. The HSE uses a unique high efficiency heat exchanger performing at up to 95% AFUE.
Condensing boiler Wikipedia. 2019-3-4 · Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain
Easy to install and clean is the most feature also high efficiency ( can be up to 99%). ZWNS seriesVaccum hot water boilers. DEVOTION vacuum hot water boiler consists of two parts: the evaporation zone and the heat exchanger. The evaporation zone is of three-pass shell boiler structure; the upper part is a steam-water heat exchanger.
2019-10-2·When electricity supplies are limited or heat is abundant, absorption heat pumps provide an alternative way to generate heat. They can be driven by any heat source, including solar energy and geothermal hot water, among others. Absorption heat pumps have higher energy efficiency than gas boilers, and can make good use of low-grade ambient heat.

Gas-fired condensing boilers are a new type of autonomous heating equipment for homes and apartments. They boast high efficiency much higher than that of conventional boilers. This efficiency level is achieved thanks to the use of heat generated by the combustion of liquid and thanks to the use of energy generated by gas combustion.
A three-dimensional (3-D) code which can predict the complete performance of high efficiency boilers is described in this paper. The model is in two parts. The combustion chamber is modelled in the first part and the heat exchanger in the second. The thermal efficiency is calculated from the predicted results.
