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.
What is combustion efficiency in steam boiler?Managing your boiler with the best amount of excess air will reduce heat loss up to the mass and enhance combustion efficiency. Combustion efficienWhat are the factors of combustion efficiency?The thermal efficiency and combustion efficiency of a condensing device will be different. The only way to determine the exact thermal efficiencyWhat are direct and indirect efficiencies in boiler?The overall boiler efficiency relies on many parameters apart from combustion and thermal conductivity. These other parameters include ON-OFF damag Boilers that don’t use heat recovery systems can waste up to 18% of heat through the flue, and more because of issues such as insufficient lagging/insulation or poor maintenance that means a build-up of deposits. You can fit boiler flue economisers to minimise waste and they can save between 5 and 15% on your heat loss depending on the type
File Size: 821KB A unique feature in the recovery boiler is a rigid cross-furnace screen at the nose arch. It protects the superheater from furnace heat radiation and thus reduces corrosion. Operator safety and ergonomics play key roles in Valmet’s boiler design, and our boilers feature many solutions that focus on them.
Bidragon Group is engaged in manufacturing and exporting steam boiler, hot water boiler and thermal oil heater, during the past manufacturing process, our technical team reach and developed more than 10 patents for increasing boiler heating efficiency, Take thermal oil heater for example, out technical team design coil tube on boiler top and which design increases our thermal oil heater’s
Cited by: 13 Waste heat recovery boilers are engineering solutions for generating steam, hot water, hot oil and hot air from gas turbines’ and motors’ exhaust gasses which are used to generate electricity. With this application, it is possible to increase the efficiency of a turbine or motor system from 40% up to 90%.
The thermal efficiency of a boiler specifies the effectiveness of the heat exchanger of the boiler which actually transfers the heat energy from fireside to water side. Thermal efficiency is badly affected by scale formation/soot formation on the boiler tubes.
The recovered heat and steam can be recycled to be used as-is, or used to heat new feedwater. The result is saving both fuel and money. There are two different approaches to heat recovery. MPN Boilers can help you create an integrated design solution that will …
Experimental Design and Set-up 3.1. Heat recovery from flue gas for fuel drying and air heater system The use of flue gas to increase boiler efficiency was divided into two parts, namely, applying the recovery heat to dry the fuel and applying it to preheat the air before entering combustion chamber, as …
Modern Method to deterMine recovery Boiler efficiency Authors*: Esa K. Vakkilainen1 performance testing of recovery boilers, mill energy wide control systems, and in calculating the air emission data. Typically, recovery where η is the boiler efficiency Q abs …
Aug 07, 2019· Waste Heat Recovery Boilers (aka WHRB) are a unique designed to heat recovery from waste flue gases from Furnace, DG, Kiln exhaust. A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.
Applications include heat recovery for turbines, waste heat, incinerators, economizers and air heaters. These custom solutions are engineered from a single-source to ensure the highest quality output. Types: MaxFire, MaxFlow, Slant-VC, Modular, Waste Heat boilers Size range: 10,000 to 500,000 lbs/hr
