Question: When the total heat input into a boiler (for example a Heat Recovery Steam Generator (HRSG)) is changed (e.g. increased firing rate, adjustment, or modification to the primary or an auxiliary heat source), resulting in the steaming capacity exceeding the original Manufacturer's Minimum Required Relieving Capacity (MRRC), does this Get Price
The impurities need not be completely removed in all cases, however, since chemical treatment inside the boiler can effectively and economically counteract them. Feed-water purity is a matter both of quantity of impurities and nature of impurities: some impurities such as hardness, iron and silica are of more concern, for example, than sodium Get Price
Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.Get Price
To maintain boiler integrity and performance and to provide steam of suitable turbine or process purity, boiler feedwater must be purified and chemically conditioned. The amount and nature of feedwater impurities that can be accommodated depend on boiler operating pressure, boiler design, steam purity requirements, type of boiler water internal treatment, blowdown rate, and …Get Price
