low temperature waste heat boiler

Low temperature heat and water recovery from

The flue gas dryer is a condensing heat exchanger between the flue gas and ambient air. As the flue gas cools, its water content condenses and can be recovered and treated for use within the plant. In general, the results indicate that low temperature waste heat and water recover from boiler flue gas would be more feasible and beneficial for

Waste Heat Recovery in the Oil & Gas Sector - Oil&Gas Portal

Electrical EnergyTraditionally, waste heat of low temperature range (0-120 °C) cannot profitably implemented for electricity generation because of the low Carnot efficiency (typically ending up with 5-7% net electricity). In the field of thermal energy direct utilization, two main options are available: waste heat recycling within the process (Fig. 2) or recovering within the plant or industrial complex.

Waste Heat Recovery Methods And Technologies - Chemical

There are two types of vapor-absorption heat pumps. The first type (Type 1) is applicable for waste heat temperatures between about 100 and 200C. They transfer heat from a high-temperature heat source (waste heat) to bring a low-temperature process stream to an intermediate temperature. LiBr heat pumps can generate a temperature output of ~100C.
