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.
Aug 27, 2018· Before condensing boilers became popular, this application would require extra valves and pumps to protect the boiler from utter destruction from low incoming water temperatures within a short period of time. Condensation in a boiler comes from cooling the flue gasses below the dewpoint.
For example, installations that have a check valve in the common pipe. The check valve typically is used as a post-design solution on a system that has difficulty supplying hot water to the system where the primary-loop, or boiler-loop, flow rate is less than the secondary loop, or distribution loop.
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.
The boiler plant in building 45 contains three new 1500 MBH condensing boilers, as well as two old steam boilers. The old steam boilers act as a backup system and transfer the steam to hot water through a heat exchanger. This heating plant serves both …
Jun 19, 2018· Water boilers are available for condensing applications or non-condensing applications. Steam boilers are available in both low and high pressure, and have designs which require the condensate to return to the boiler or models for producing industrial steam for process, without condensate return.
What Are the Differences Between Condensing and Non-Condensing Boilers? The main difference is that condensing boilers are up to 99% efficient while non-condensing boiler are only up to 78% efficient. This means that condensing boilers help you save up to £310 per year on gas bills while also reducing your household emissions.. If you want to replace your old boilers and you are looking into
Figure 1. Condensing boiler with an indirect DHW system and outdoor reset control . Condensing boilers achieve high efficiencies because they can recapture the latent energy from the moisture in the combustion gases when those gases condense. For condensing to occur, the boiler’s heat exchanger surface temperature must be
Food must often be heated or boiled during processing. Thus this industrial sector obviously needs plenty of thermal energy. However, some steam applications are still stunning; a good example is potato processing. Breweries. Most people know that a good and tasty beer consists of hops, malt and water.
Applications and Piping Strategies for Condensing Boilers Webinar Objectives: 1. Control objectives for hydronic systems 2. Review of hydronic fundamental principals 3. System control and piping strategy for condensing boilers 4. Introduction to NEW Vitodens 100 Application Guide
Condensing boilers, however, have one heat exchanger, while condensing tankless water heaters have two. Combi boilers have a stainless-steel flat-plate heat exchanger separating the central-heating water supply from the domestic-hot-water water supply. Central-heating operations of a condensing boiler can be controlled via thermostat.
Typically non-condensing boilers cost about a third of the cost of a condensing boiler. Principal-2 80˚F ( – Select Heating Coils for a 27˚C ) Leaving Water Temperature Proper heating coil selection is the most important element of designing a high-performance heating water system.
