Three Ways to Optimize Solid Fuel Combustion - Hurst Boiler

Be careful not to reduce the under-fire air so low that the boiler loses combustion. This can be dangerous as a system may react by ramping the fan rates which will cause more of the fuel to volatile and fill the furnace. If these gases were suddenly sparked,

Figure 3.11.5(b) again shows the formation of steam at 10 bar g, but this time the boiler is fed with feedwater heated to 70 C by returning more condensate. The increased enthalpy contained in the feedwater means that the boiler now only has to add 489 kJ/kg of heat energy to bring it up to saturation temperature at 10 bar g.
