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.
A boiler generates 5000kg of steam per hour at 2Mpa the steam temperature is 325'c and the feed water temperature is 50'c. The efficiency of the boiler is 80% when using oil of Higher Heating Value 45500kJ/kg. The steam generated is supplied to a turbine which develops 500kW and exhausts at 0.2Mpa, the quality of the steam being 0.98.
Jul 28, 2006· one boiler horsepower is 33,475.3 BTU/hr. The equation for calculating boiler horsepower is. BoHP = w(h2-h1)/33480. where w is the weight of the steam produced. h2 is the enthalpy of the steam leaving the boiler. h1 is the enthalpy of the water entering the boiler. To be correct the enthalpy of the water should be at the pressure of the boiler.
A boiler generates steam at 40 bar and 390°C. This steam then goes to a turbine where it expands adiabatically and reversibly to 8 bar. The steam next goes to a superheater, in which the pressure drop from inlet to exit is 1 bar, with the exit temperature being 390°C .
1 litre of furnace oil used in boilers can be totally substitute by 3.5 kg of biomass on the basis of .. 18-ton heavy fuel oil fired steam boiler to run using wood. . 10 kg/cm2. Quantity of fuel oil consumed. 567 kg/hr. Feed water temperature. 80° C. New condition and coal fuel fired 1 ton steam
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F.
File Size: 141KB Boiler Horsepower - BHP. The Boiler Horsepower (BHP) is the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 ℉, with feedwater at 0 Psig and 212 ℉. “Boiler horsepower, a unit of measurement of power of steam boilers” from Wiki.
Example: Producing 1 t of saturated steam at a pressure of 1 bar (boiling point 100 °C) requires tank for the boiler feed water (this tank should be insulated). . In the heat/power cogeneration process implemented in this company, natural gas is To evaporate 1 kg of water 1.1 kg of steam is required, if …
To answer this question we need to make several assmptions. 1. To make one kg of steam we need one kg of water. 2. Let water be at room temperature of say 20° C. 3. No loss of heat in heating the water from 20°C to its boiling point 100° C or conv
Lbs Steam delivered per Hour. Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions. BTU - British Thermal Units. Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British
The evaporation of 34.5 pounds of water per hour from and at a temperature of 212 f is defined as: A. 85when testing the low water fuel cutoff on a steam boiler the burner shoud be firing why? A. 90 where is the breeching located at for a steam or hot water boiler? A. A below the fire box. B.
