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.
Feed water composition. In order to generate steam on a constant basis, boiler should be continuously supplied with water, called as feed water. Feed water consists of condensate, which gets collected after the steam gets condensed by losing heat to the process or radiation losses, flash steam and make up …
Focusing only on the periodic "tuning" of a boiler often results in masking field device issues that build up over time. Many boiler measurements can be challenging because of the physical design of the process, fuel variability and other issues, but proven technologies exist to deliver desired business results.
BOILER FUEL CONSUMPTION What is the fuel consumption of a 10,000#/hr steam boiler using diesel as fuel (VHI = 130,000 BTU/gal) with a feedwater temperature of 154 °F? FC = [ SP * ( hs – hw ) / ( BE * VHI ) ] Microsoft Word - Johnston Boiler Company Boiler Glossary
As with other gases, the composition of flue gas depends on the type of fuel and for flue gas desulphurization on a coal steam turbine power plant; 1 – boiler . Ask Price View More; Flue Gas Analysis in Industry – Testo 350 Portable Emission Analyzer. Table 5: Relative exhaust gas composition in % under different gas conditions.
Another boiler fuel is referred to as biomass. Biomass is renewable organic matter. Examples of Fuels fired in boilers to generate hot water or steam Fuel Description The chemical composition of coal is also determined in a laboratory by chemical analysis. Results
Fuel waste due to boiler scale may be 2% for water-tube boilers and up to 5% in fire-tube boilers. Energy losses as a function of scale thickness and composition are given in the table below. Steam Motors Compressed Air OFFICE OF INDUSTRIAL TECHNOLOGIES ENERGY EFFICIENCY AND RENEWABLE ENERGY • U.S. DEPARTMENT OF Fuel Loss, % of Total Use
Composition of Air Combustion in Steam Boiler The steam boiler must have sufficient supply of air to make combustion properly. Air is one of three important parts for combustion to take place, Air-Fuel-Heat. The air for combustion contains based on volume, 21% Oxygen (O 2) and 79% Nitrogen (N 2). The Nitrogen does not have any role and is not
An industrial scale oxy-heavy oil fired boiler demonstration project was conducted by a Japanese consortium in 1993–2000. 2, 3 The goal was to develop a high performance boiler by combining oxy-fuel firing and a condensing heat exchanger to achieve a boiler efficiency of 105% LHV (98.9% HHV) and low NOx emissions. A pilot scale boiler was
A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.
On the optimization of boiler efficiency using bagasse as fuel chemical composition given by Hugot. i. different heat losses, heat transfer surfaces or refuse collected η, is plotted as a function of the stoichiometric ratio at the exit of the boiler and the steam power, demonstrating the global effect of heat losses on boiler
