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.
File Size: 296KB To store the fuel for a wood chip boiler, one needs much more room than for storage of wood pellets. Wood chips will weigh ca 200-250 kg/ m3 loose volume, wood pellets ca 650 kg/m3 loose volume. What moisture content fuel do I need for my boiler? For a domestic boiler (up to 100 kW) one needs a relatively dry fuel of 20-25% MC on total weight
I will give you an example, so you can take this as reference and calculate fuel required for any capacity of Boiler for any fuel. Boiler Capacity - 1000 kg/hr Steam Pressure - 10.5 kg/cm2(g) Steam Temperature - 185.5 Deg c (Saturated Steam)- You
Energy Tips STEA Steam Tip Sheet 4 Improve Your Boiler’s Combustion Efficiency Combustion Efficiency Operating your boiler with an optimum amount of excess air will minimize heat loss up the stack and improve combustion efficiency. Combustion efficiency is a measure of how effectively the heat content of a fuel is transferred into usable heat.
If steam is extracted from the turbine at a pressure of 500 psia, energy/mass balance calculations show that the flow rate to the heater should be 20.8 percent of the total steam flow. The
Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.
To arrive at a Boiler Size requirement , we have provided some Boiler Efficiency Calculations for you to determine the boiler size you may required. In addition we have provide other programs to determine Boiler Operating Cost, based on Steam losses, which might be happening in your system.
Heat Loss · Saturated Steam · Steam Turbine · Preferences · Header · 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.
Online calculator to quickly determine Boiler Efficiency. Includes 53 different calculations. Equations displayed for easy reference.
In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where, Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg)
Procedure to Determine a Biomass Boiler’s Fuel-Heat-Input-To-Steam-Output Ratio Last Revised May 2014. Conduct at least three valid stack test runs; each at least 60 minutes in duration. Follow Steps 1 through 8 for each run. Calculate the arithmetic average value for fuel-heat-input-to-steam-output ratio considering the results of all valid
Steam Properties · Boiler · Steam Turbine How to Calculate Boiler Heat Input Rate. Depending on its energy source, a boiler may get its heat from the flow of electric current or from burning fuel. Each of these sources offer its own method for calculating the boiler's heat input rate. A separate method, however, works for all boilers. The boiler's
