waste heat recovery boiler Agent cold start up

Warm-start versus cold-start | Fuel Oil News

Most waste-heat-recovery devices transfer heat from a high-temperature effluent stream to a lower-temperature input stream. They can either increase the temperature of the input stream, or change the input stream from a liquid to a vapor, as in a boiler. All these de - vices can be broadly categorized as heat exchangers. Waste heat can also

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water

On energy auditor's suggestion, a waste heat recovery boiler was installed to recover heat from exhaust gas and generating 800 kg/hr of saturated steam at 10 kg/cm 2. The waste heat recovery boiler operating data are given below. Feed water temperature = 60°C. Enthalpy of steam at 10 kg/cm 2 = 660 kCal/kg.

How do Waste Heat Recovery Boilers Work? – Thermax Ltd

In any study of waste heat recovery, it is absolutely necessary that there should be some use for the recovered heat. Typical examples of use would be preheating of combustion air, space heating, or pre-heating boiler feed water or process water. With high temperature heat recovery, a cascade system of waste heat recovery may be practiced to

Waste Heat Reduction and Recovery for Improving Furnace

Cold starts place a much greater mechanical load on shell boilers than normal operation. A cold start is unavoidable the first time the boiler is commissioned. However, procedures similar to cold starts can also occur after initial start-up, e.g. after the boiler has been left idle for some time or in the case of
