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.
Mark Crowther, Technical Director, Kiwa Gastec Last month we reported on a two year project in Leeds to investigate how hydrogen could be used for domestic and commercial heating in place of natural gas. Mark Crowther, technical director at Kiwa Gastec, makes the case for conversion. It’s a well known fact that the Climate Change Act […]
A conventional boiler for use on natural gas only can run perfectly well with up to 20% hydrogen in the mix, says Bridges, but some changes in the technology are needed for more than 20% hydrogen. ‘The hydraulics, the water system, the pump, the heat exchangers are the same; it’s primarily the ignition system and combustion of the hydrogen
In comparison, hydrogen heating is a far better alternative to natural gas boilers in terms of carbon emissions. Unfortunately, producing low-carbon hydrogen is currently very expensive. Making low-carbon hydrogen production cost effective is, in part, what the £20m of funding for the Hydrogen Supply Programme is aimed at addressing.
Author: Emily Gosden When the hydrogen comes in to contact with oxygen it also generates heat and water as a byproduct. A hydrogen Fuel cell Boiler is a home unit that utilizes this waste heat for hot water and heating, while also generating electricity for the home. Boilers that generate heat and electricity are also known as Combined Heat and Power units, or CHP.
Pure Energy ® Centre Senior Engineer, Mr. Vincenzo Ortisi said that “the Hydrogen Boiler is a condensing gas boiler fuelled by Pure Hydrogen ®. Like any other natural gas boiler, this device is designed for radiant heating such as under-floor and space heating.”
Nov 22, 2018· Millions of gas boilers will need to be replaced with hydrogen alternatives and coupled with electric heating devices if Britain is to hit its carbon targets at the lowest cost, according to the
Apr 12, 2019· A review of the current evidence on emissions and air pollutants that could be associated with a hydrogen-for-heating supply chain.
Hydrogen and fuel cell technologies for heating: A review A catalytic boiler passes hydrogen gas over a highly reactive metal catalyst, which undergoes an exothermic chemical reaction to produce heat for space and hot water heating without a flame. Hydrogen and fuel cell technologies for heating markets lie at the intersection of these
Apr 19, 2020· How it works. The first hydrogen-powered domestic boiler in the world is based on a catalytic burner fueled by hydrogen gas. Within the reaction channel, a self-priming catalyst agent activates the oxidation process, with no need for electricity. Low-concentrated hydrogen combines with the oxygen in the surrounding air; this reaction produces thermal energy, or in other words heat.
