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.
Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
How to Calculate Power Plant Cost 2017-08-11 16:08:55 Power plant . Electricity is the most exciting form of energy human beings have discovered so far. In the power supply, the main function of the power plant boiler is to convert the fuel combustion heat into steam heat , …
Can the facility use the waste/recycled heat? When the heat is not utilized, the system is operating at ≈ 30% to 35% When the heat is being utilized, the system can operate up to 80% to 85% Without long hours of operation (>3,000 hrs/yr) with at least 50% usage of the recycled heat (annual basis), the viability of CHP is low.
Key features of TTNA Waste Heat Boilers. Steam flow - 2,000 to 200,000 lbs/hr; Steam pressure up to 1500 Psi - Single or multiple pressures; Saturated or superheated steam - up to 950 F (steam temperature depends on waste gas characteristics).
May 01, 2019· Table 2 shows values for other design parameters assumed for this application of the model. The boiler produces 350 psig saturated steam from preheated boiler feed water. Heat flux, tube wall temperature, and corrosion implications Heat flux is a very important factor in the reliability, life cycle cost, and the safe long term operation of the WHB.
Knowing the Cost of Steam C.Percentage of make-up water or percentage of condensate return Normal condensate returns have a higher Btu content than make-up water. Today’s industrial benchmark for condensate return is 90% if the plant is not injecting steam for the process. D. fi eBflecrienocyi Higher boiler efficiency lowers steam cost
Chemical plant incineration; Hazardous waste and municipal solid waste incineration; Open bottom A type for solid-fuel burning systems; Design features to accommodate high cycling operation . Fire Tube Single Shell, Single Pass. The fire tube single shell, single pass boiler is a simple, low cost solution for sub-critical waste heat boiler
fired heaters/furnaces. In both cases, waste heat recovery can lead to substantial fuel savings. Process heat from steam boilers Recovering waste heat often reduces the need for steam in a plant. Consequently the boiler’s fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system.
A boiler feedwater and blowdown separator was included as part of the package. Installing the waste heat boiler system recovered about 2.58 MM BTU/hr of energy, lowering the stack temperature to 338°F. The addition of the waste heat boiler on this application saved the facility $216,770 per year.
The 120 ton chemical waste heat boiler purchased by the large chemical industry customers to our company was applied to the 600 thousand ton / year methanol to olefin project, and the project has been put into operation in October 2017.
