Deviations from the standard conditions can result in a <br /> change of values within the heat balance,and must be taken into consideration in the layout of the cooling circuit/equipment <br /> (intercooler;emergency cooling;...). In the specifications in addition to the general tolerance of+/-8%on the thermal output a <br /> further reserve of 10%is recommended for the dimensioning of the cooling requirements. <br /> CH4>50 Vol.%required for specified NCx-emissions <br /> 19.04.2011/2 TS JGS616 E22 4160V April 19 2011 Ameresco Forward LFG-WES <br /> 4/32 <br />
