Boiler Economizers and Waste Heat Recovery

Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%. II Applications Conventional stack economizers are more effective where a smaller volume of water needs to be heated to a higher temperature. They are commonly used to preheat boiler feed water.

Sludge Dryer | Sewage Sludge | Paper Sludge - Tianli Energy

The temperature of the boiler flue gas after denitration by SCR method is above 300 °C, and the low oxygen content ensures the safe and reliable sludge drying process. At the same time, the drying temperature is moderate to avoid the formation of dioxins and reduce the v olatilization of foul gas during the drying process.

A novel technical route based on wet flue gas

May 05, 2020 · The flue gas temperature-humidity chart for LDD-WFGD system is shown in Fig. 10. The raw flue gas temperature was set at 130 °C (①). After passing by low-temperature economizer, the temperature decreased to T g,in = 90 °C (②). After the process of desulfurization (③) and dehumidification (④), the temperature continued to decrease.

as a desiccant. The CES process involves direct heat transfer between the hot gas stream and a cold circulating water (desiccant) stream accompanied by dehumidification of the flue gas, in a packed bed column. The heated desiccant that leaves at bottom of the packed bed column can then be used as a source of heat for other operations.

Simulation of a flue gas driven open absorption system for

Jan 01, 2017 · 1. The system uses the high temperature flue gas at the outlet of the boiler furnace as the regeneration source of the liquid desiccant and does not need additional high quality energy input. 2. By using the open absorption system, the flue gas can be processed to a low humidity ratio at a temperature higher than the dew point.

Gas Dehumidification | PermSelect-MedArray

Gas stream dehumidification using PermSelect® membrane gas dryers is achieved as illustrated in the figure above where the humid gas stream is supplied to a port at one end cap of the membrane gas dryer. As the humid gas flows through the lumens of the membrane dryer, water vapor is transferred across the membrane driven by the higher partial pressure of the water vapor in the humid gas stream compared
