How to calculate the gas consumption of gas boilers ...

Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization. For example we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600000 kcal (fixed value) the natural gas calorific value is 36.22 MJ/Nm3 (fixed value) and the thermal efficiency is 92% (non-fixed value). According to the actual situation of the boiler the calculation is carried out.

How do you calculate Boiler HP dosing system capacity

Jul 21 2020 · Let us calculate phosphate consumption. Percentage of blow down =Make up % X Feed TDS / (Boiler TDS-Feed TDS) = (5/100) X 5 X 100 / (50-5) =0.55%. Water loss in blow down = 100 X 0.55/100 =0.55 TPH =550 kg/hr. Loss of phosphate in blow down water = (Residual phosphate X Blow down) / 1000. =8 X 550 / 1000 =4.4 Gm/hr.

How do you calculate the Power generation in steam Turbines??

Aug 11 2020 · SO total power developed at Turbine shaft P = P1+P2+P3 = 3.53+16.82+6.46 = 26.81 MW. Specific steam consumption SSC = Turbine inlet steam flow / Power generation = 145 / 26.81 =5.41 MT/MW. So by increasing the bleed steam flow the work done by the Turbine decreases & hence steam consumption will increase.
