low pressure recirculation pump for waste heat boiler

BOILER FEEDPUMP RECIRCULATION

feedwater valve reaches 10% to 25% of pump capacity, the recirculation valve will go closed. This recirculation valve will remain closed until the pump flow falls below the 10% to 25% level, at which time the recirculation valve will automatically open to guard against the rapid heat and pressure rises.

Boiler Circulating Pump Hot To Touch? (Possible Causes

The raw syngas from the gasification island is cooled in waste-heat boilers, recovering heat while generating steam at medium- and low-pressure level before being sent to the AGR unit for H 2 S removal. Depending on the AGR system employed, a COS hydrolysis step may be required.

Boiler Circulation Problems Troubleshooting Easy Step-by-Step

The efficiency of generating power from waste heat recovery is heavily dependent on the temperature of the waste heat source. In general, economically feasible power generation from waste heat has been limited primarily to medium- to high-temperature waste heat sources (i.e., > 500 oF). Emerging technologies, such as organic
