The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Equation 52 can then be used to calculate the : Example 52 A is rated at 000 kW (kJ/s) and operates at 10 bar g with a feedwater of 50°C How much can be generated? Where from using the tables on the website:
Temperature = 4679 °C [Steam Property Calculator] => Specific Enthalpy = 14691 btu/lbm; Steam Energy Flow = Specific Enthalpy * Mass Flow [ Steam Energy Flow = 48049 = 14691 btu/lbm * 310 klb/hr] Step 2: Determine Feedwater Properties and Mass Flow The feedwater flow rate can be calculated from steam mass flow and blowdown rate:
Fuel Energy = Energy / Combustion Efficiency [ Fuel Energy = 45792 = 32787 / 0716 ] Assumptions Deaerator provides feedwater near the boiling for the deaerator's set operating pressure (Saturated Liquid) and Blowdown Pressure are the same
Output: 3 ton steam boiler: Steam Temperature: Rated steam pressure: 07Mpa/1Mpa/125Mpa/16Mpa/245Mpa: Fuel: Oil/gas fired: Feed temperature: 20 Structure: Fire tube
· 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 as a saturated liquid at pressure
can be expressed in Horsepower MBTU or in Pounds of delivered per hour Sponsored Links load - the capacity of a - is often rated as horse powers lbs of delivered per hour or BTU
