Dry saturated steam at 3 bar g is used to heat water flowing at a constant rate of 1.5 l/s from 10°C to 60°C. hfg at 3 bar g is 2 133.4 kJ/kg, and the specific heat of water is 4.19 kJ/kg °C. Determine the steam flowrate from Equation 2.6.7: As 1 litre of water has a mass of 1 kg, the mass flowrate = 1.5 kg/s. ### How to Calculate Boiler Steam Flows | Hunker

Mar 17, 2015 · The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate; Steam Mass Flow = Feedwater Mass Flow - Blowdown Mass Flow; Steam Mass Flow = Feedwater Mass Flow - Feedwater Mass Flow * Blowdown Rate; Feedwater Mass Flow = Steam Mass Flow / [ 1 - Blowdown Rate] ### boiler makeup water calculation CFBC Boiler Manufacturer

How to Calculate Boiler Steam Flows | Hunker ### Boiler water consumption - Lenntech

Moreover, the water consumption is usually determined with the blow-down brine, depending on the recirculated steam and the make-up water concentration. B=S x (1 - r) x m / b - m. B = Blowdown. S = Steam rate. b = boiler water TDS concentration. m = make-up water TDS concentration. r = fractional condensate return ### Methods of Estimating Steam Consumption | Spirax Sarco

How to Calculate Boiler Steam Flows | Hunker ### Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss ### WASTE HEAT TO POWER SYSTEMS - US EPA

Waste heat is found in the conservation of energy equation for a heat engine. Q H = Q L + W. Where. Q H is the input heat to the system from a given fuel, W is the useful mechanical work attained from the system and. Q L is the waste heat.
