Type of fuel fired = Paddy husk In a process plant a coal fired boiler of 78% efficiency is proposed to be replace with paddy husk .

Read MoreWithin the sub systems of a coal-fired power station, the task of a boiler is to produce the correct mass flow rate and temperature of steam which is passed to the steam turbines for the generation of electricity. For a drum-type boiler, steam generation starts with the combustion of pulverised coal and air in the furnace of the boiler arrangement.

Read MoreCoal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

The high creep strength of Sanicro ® 25 combined with its good corrosion resistance makes it an extremely suitable option for use in superheaters and reheaters in advanced coal fired power boilers. Use in high temperature applications in other types of steam boilers employing different fuel types is also possible.

Read MoreAnswer (1 of 4): It all depends on the Calorific value of the fuel, efficiency of the steam generator and the enthalpy of the steam you required. Herewith I am giving you formula u could calculate the amount of fuel required. Let us consider GCV of coal as -4000 kcal/kg CFBC boiler efficiency-8

Read MoreOct 20, 2011 · No, pressure will increase when the boiler is fired. You have adjusted your pressure reducing valve but you may not have adjusted it enough. I'd suggest adjusting it very low and "sneaking up" on your desired pressure from lower to higher. Then you'll know for sure if the pressure valve is bad. Cold pressure should be no more than about 12 psi.
