Maintain 30% air flow and purge the boiler for at least five minute and check turbine bearing lubricating system. Check that all the feeders and mills are off,break the vacuum when turbine speed comes to zero. Individual burner HO, atomizing air and steam nozzle valves and Igniters valves are closed.

Learn MoreWhen considering boiler energy savings, invariably the discussion involves the topic of boiler efficiency. The boiler suppliers and sales personnel will often cite various numbers, like the boiler has a thermal efficiency of 85%, combustion efficiency of 87%, a boiler efficiency of 80%, and a fuel-to-steam efficiency of 83%. What does these mean?

As an illustration, the optimum value of air excess to the combustion of natural gas is 5 to 10%, liquid fuel at the rate of 5 to 20%, and 15 to 60% for coal combustion.

Learn MoreFor units burning bituminous coal, EPA calculated that at least 40% of the heat input would have to come from coal and the remainder from biomass. For other fossil fuels, the heat input percentages were found to be at least 30% for heating oil and 10% for natural gas and the remaining heat input from biomass.

Learn MoreCalculation of the work output, boiler heat input and efficiency of this example becomes slightly more complicated, as in this case work is done by two separate steam feeds to the turbine and heat

Learn MoreFor high temperature flue gases it is common to use a steam boiler, commonly known as heat recovery steam generator (HRSG), to produce high pressure (usually >50 pounds per square inch gauge psig) steam and use this steam in a turbo generator to produce electrical power. In this case, the working fluid is

Learn MoreBased on load profile as shown in graph below. For heating steam boilers from 50 to 600 BHp or 10,000 to 70,000 Steam Lbs/Hr.
