Auxiliary Boiler Clause Samples

Auxiliary Boiler. The auxiliary boiler shall be a fire tube, low emission, gas-fired, natural circulation, packaged type boiler complete with single gas burner, motor-driven forced draft fan, electronic programming and flame safeguard controls, boiler limit and fuel safety interlocks, fully automatic combustion controls, feed water regulator and control panel. The auxiliary boiler provides steam until the HRSG begins providing steam and sparging steam upon plant shutdown. During initial start-up (i.e. with no cold reheat or HP steam available), auxiliary steam will be provided by the auxiliary boiler at 125 psig saturated. The auxiliary boiler is fired by natural gas from the Fuel Gas System. Make-up water for the auxiliary boiler is supplied from the demineralized water system, with the water deaerated by the auxiliary boiler deaerator. Two relief valves protect the auxiliary boiler from over pressurization.
