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.
Steam Flow Rate versus kW Rating - Calculate steam flow rate when kW rating is known; Steam Heating Process - Load Calculating - Calculating the amount of steam in non-flow batch and continuous flow heating processes; Stress in Steam Boiler Shells from Boiler Pressure - Calculate stress in in steam boiler shells caused by steam pressure
Steam Flow Measurement • Measuring Steam Energy Internal area (ft 2) Density (lb/ft 3) Mass Flow Rate (lb/hr) Energy Rate (Btu/hr) Enthalpy (Btu/lb) Basic steps for the steam energy calculation ∗Steam is a compressible fluid ∗Density is a function of both temperature and pressure
Boilers and steam generators. A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam — the process of boiling. This produces steam at a rate that varies according to boiler operation.
Pump Flow Rate. Each pump on a boiler feed unit is sized based on the total load of boilers fed by specific pump feeds at one time. For boiler feed pumps running ON/OFF, the pumps are controlled by a boiler level controller.
The air flow rate to CASU producing the maximum hydrogen generation rate per unit steam mass flow rate rises as the steam mass flow rate upsurges, excluding the steam mass flow rates of 1 kg/s to 20 kg/s. When the content of carbon in coal drops, an inferior air mass flow rate to the CASU is required to yield the maximum hydrogen generation rate.
Boiler air flow (or air flow on a forced or balanced draft furnace) may be measured with a pitot tube, air foil section, or any calibrated flow restricting device located in the duct that leads from the forced draft fan to …
Boundary flow scaling is adopted for feed water flow, steam flow rate, accumulator injection, and GDCS injection in addition to the steam flow rate into the ICS as well as condensate flow rate from ICS to the main heat transport system. It simulated one full-size channel of the main heat transport system of the prototype so that its volume and
Steam Energy Flow = Specific Enthalpy * Mass Flow [ Steam Energy Flow = 103,269 = 1,634.1 btu/lbm * 59.9 klb/hr] Step 2: Determine Feedwater Properties and Mass Flow The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Blowdown …
We will use a standard LI-60, insulated kettle with a maximum steam flow rate at 30 psi of 140 lbs. We are delivereing 150,000 Btu (145,500 lbs. of steam) by using a boiler with 300,000 Btu input and 50% efficiency note: these are reasonable numbers for boilers or …
The boiler uses 147l/hr of fuel, the water inlet temperature is 25degrees Celsius and its maximum steam output is 2tonnes/hr. my aim is to determine the steam flow rate at a lower pressure than
Dec 29, 2019· Homework Statement:: Natural gas is burned in a shell and tube boiler to raise 5 tonnes per hr of dry saturated steam at 4.0 bar g. Condensate is returned to boiler at 4.0 bar g., 100 degrees C. i) calculate mass flow rate of natural gas required (kgs-1) ii) the steady state heat supplied to the heating application (MW)
