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.
Oct 03, 2017· For example, if a boiler is in the basement, and its a 2 story house with baseboard radiation on the second floor, it could be 8' + 9' + 1' = 18' (boiler to upper baseboard). 1 PSI / 2.31 = 0.4329 18' x 0.4329 = 7.7922 minimum PSI required cold temp
File Size: 63KB Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.
Jul 03, 2019· Q: What is the formula to convert steam temperature into pressure? The question asks for a formula so here is a very good estimate that is good enough for most purposes. Saturated steam temperatures and pressures are related by a power curve relat
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in 2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.In SI units, 1 psi is approximately equal to 6895 N/m 2.
Boiler Horsepower What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? The factor of evaporation is 1.08. BHP = (LB/HR*fe)/34.5 BHP Boiler Horsepower BHP = (LB/HR*fe)/34.5 Lb/Hr Pounds per Hour BHP = 21500 * 1.08 / …
High Pressure Steam Boilers / Atmospheric. 150 PSI Models & Ratings / Natural Gas Fired. Rev. 3/2014. STACK / DRAFT REQUIREMENTS •UL listed for use with Type B Vent. •Minimum stack height including Draft Control is 10 feet. •The stack should be supported independently of the boiler and an adjust-
A few months ago I had a new Utica steam boiler installed. I noticed the pressure is getting much too high before the burner cuts off. It is getting up to 2.5 PSI which I …
For the low-pressure steam typically used in heating systems, that ratio is 1,194 BTUs for every pound of steam the system provides. If your boiler supplies 400 pounds of steam per hour, for example, you would multiply 400 pounds by 1,194 to arrive at a figure of 477,600 BTUs.
Unit of: Pressure, Stress Jan 31, 2013· Hg = enthalpy of steam, in Btu/lb. hf = enthalpy of boiler feedwater in Btu/lb. ηB = true boiler efficiency (per ASME PTC 4.1 method) 1,000 = cost measured in units of 1,000 lbs. per hour. In this simplified calculation method, the formula assumes that one boiler is being used, one fuel and a single steam pressure. True Boiler Efficiency (ηB)
Often it is necessary to convert a measure of capacity from one term to another. The conversion table will allow you to quickly convert various measures of capacity. The table and formulas can help you size and pick out components such as condensate pumps and boiler feed pumps. Some additional conversion factors that may prove helpful are shown below.
