BORSIG WASTE HEAT BOILERS FOR PROCESS HEAT EXCHANGER NIT
Estimates of the amount of industrial waste heat available at a temperature high enough for power generation with todays technologies (i.e., >500 o F) are in the range of 0.6 to 0.8 Quads (or 6,000 to 8,000 megawatts [MW] of
May 14, 2013 · Its temperature is about 404 K when the gas is discharged from the heat recovery boiler. In the rear of the sinter cooler, air at ambient temperature was introduced to the sintered bed and the gas temperature at the outlet is low. This part is called the non-heat recovery region.
Sintered ore temperature at outlet of cooler rise approx. 30 deg.-C in circulation type. Temperature difference is small enough not to affect sinter plant commercial operation.

Feb 27, 2020 · Sintering steam is still produced at the factory in a liquefied petroleum gas (LPG) heated boiler. Steam boiler feed water comes from the municipal water mains with an inlet temperature of 6-7°C and is heated to about 60°C by direct heat recovery. The
Jun 01, 2019 · The inlet air comes from the waste heat boiler. The temperature of the waste air is 404 K under the standard condition. The temperature fluctuations are limited to 20 K to avoid affecting the normal production of waste heat boilers,
