gas central heating boilers 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.
Gas Central Heating Boilers. Gas central heating boilers are responsible for heating many thousands of homes across the UK. While they can seem expensive to install, they are far more effective over time since they are operating at an impressive 90%+ rate of efficiency.
Modern oil boilers have equal efficiency to gas central heating systems. Developments by leading manufacturers over recent years have greatly improved the efficiency of oil fired boilers which is ideal due to dramatic increases in oil costs. gas central heating boiler for sale;
2019-5-11 · 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

Gas central heating boilers. by Chris Woodford. Last updated: April 10, 2018. A few hundred years ago, people would have given an arm and a leg to have central heating in their homes. Just imagine the inconvenience of having to light a wood and coal fire in every separate room to keep your house warm.
2019-5-24 · What are electric central heating boilers and how do they differ from gas boilers? Simply put, an electric boiler will use electricity to heat water up, rather than gas. A heating element will be used so that as the water runs through the boiler, it can pass over an element and be warmed up.
2019-5-22 · Based on the average energy consumption of the UK for heating and hot water (13,500 kWh), the gas and electric heating costs are as follows. The running cost of gas boilers is approximately £607.50 per year, which is much lower than the £2,160 cost for a fully electric central heating system.
Electric Boilers / Electric Central Heating Boilers – 0.5kW to 45kW. Electric Boilers – With over 2 million homes in United Kingdom at present are without a mains gas network supply, also many older houses have flue restrictions or are listed buildings that prevent the use of a gas or oil boiler on site.
