Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Solid fuel boilers | European Commissi

Energy label. New solid fuel boilers with a rated heat output of 70 kW or less are labelled on an energy efficiency scale ranging from A+++ (most efficient) to G (least efficient). Energy labelling rules also apply to packages that include a combination of a solid fuel boiler, supplementary heaters, temperature controls and solar devices.

Boiler Efficiency Improvement & Heat Loss Explained

Boiler Efficiency Improvement Steps: After Analyzing heat losses in industrial boilers, boiler engineers or technicians can help you to increase your boiler efficiency by 6% – 10%.. Here are the few boiler efficiencies boosting steps listed below:. Complete combustion of fuel so that no unburnt is left behind is a good practice and will add to the boiler efficiency.

BOILER EFFICIENCY GUIDE - Cleaver-Broo

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 key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units

Solid Fuel Boiler - Boiler Gui

Types of Solid Fuel Boiler. Because of the nature of solid fuel, there is a much more limited range of systems in which a solid fuel boiler can run with. These systems are often very aesthetically pleasing, with a rustic old-world feel and the often rare sight of a fire running in a modern household. The types of systems include: Stoves

Boiler Operations That Affect Efficiency (Part

Optimizing boiler and steam system efficiency is more important than ever. Although a boiler’s efficiency is primarily a result of its design, an operator can maintain or significantly improve efficiency by effectively managing various techniques and key functions. Read Part 2 of this two-part series which discusses key operation functions.

Boiler Efficiency - Engineering ToolB

Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the

Solid-fuel firing - ScienceDire

There is a tendency these days to view the firing of any solid fuel in a fixed bed as out-of-date but this is a superficial judgement. In the smaller boiler sizes, as for example in the domestic and small commercial range, there is as yet no established alternative to burning the fuel in some form of fixed bed.

Boiler Fuels, Emissions and Efficiency - CED Engineeri

Residual oil Crude oil and fuel oil Nos. 1 and 2 that have nitrogen content greater than 0.05 wt %, and all fuel oil Nos. 4, 5, and 6 as defined in ASTM D 396 (Refs. 2 and 5). Solvent-derived fuel Any solid, liquid, or gaseous fuel derived from solid fuel for the purpose of creating

Boiler Fuels - AutomationWi

Each and every fuel whether it is in solid, liquid or gaseous form is explosive and can prove hazardous if not used according to the recommended safety guidelines. “When monitoring the efficiency of a combustion process, it is important to know the fuel being burned since this information will help not only determine a boiler’s optimal

Improving Solid Fuel Fired Boiler Efficien

In case of conventional manual fired solid fuel boilers, the gap between the indirect and direct efficiency is quite high. Generally, the typical efficiency guaranteed is somewhere around 73-77%. The efficiency which is actually obtained lies in the range of 50-55%.
