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.

fuels are used to reduce emissions or improve boiler performance. Fuels commonly fired in boilers include fossil, biomass, and RDFs as well as other types of fuels and fuel combinations. Coal, petroleum-based oils, and natural gas are fossil fuels commonly fired in ICI boilers. However,
Flue Gas Waste Heat Boiler Thermal Efficiency Calculation 2017-10-04 17:02:11. Boiler heat efficiency refers to the heat input into the boiler, most of which are absorbed by the boiler heating surface to produce water vapor, which is the heat that is effectively utilized, and the remaining heat is called heat loss. The heat efficiency of a flue gas waste heat boiler is the percentage of the
2017-9-9·Keyword: CFBC Boiler Manufacturer, bagasse fired boiler flue gas composition FAQ about bagasse fired boiler flue gas composition 1.Why choose ZG as bagasse fired boiler flue gas composition manufacturer? We have over 70 years' experience of industrial steam boiler and autoclave,and we have a professional installation and after-sales
Alternate Approach Used to Determine the Flue Gas Temperature for Natural Gas Combustion There is another approach that can be used to determine the flue gas temperature from a natural gas furnace . The attached diagram uses the Percent Excess Air and the Percent Available Heat (this is the percentage of input energy that is delivered). 1.
Cited by: 1 A bagasse fired boiler equipped in a sugar mill is producing 80 MW of heat (steam power) at the operating efficiency of 62%. Combustion efficiency of the boiler is 92%. The composition of the bagasse on dry basis is: C = 48.1%; H2 = 6.25%; N2 = 0.1%; O2 = 44.4%, S= 0.05% and Ash = 1.1% The bagasse is burned with an excess air factor of 1.32 and

Flue gas composition is significantly affected by the combustion conditions. Concentration of gaseous species upon firing 1.7% S coal (chemical composition is given in Table 1) was calculated at 1300 °C, assuming thermal equilibrium, and presented in Figure 2 as a function of air–fuel ratio. In this chapter, air–fuel ratio is defined by the ratio of their weights; air–fuel ratio of 10
The average temperature of flue gases in air reheater is 350°C, there is no any economizer used in power system, gas temperature flow through boiler presented in Figure 2. Total enthalpy determined according to general form of perfects gas when temperature and specific heat capacity is known; used equation (4), the enthalpy of flue gases
Flue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat. Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel.
