Other waste heat sources that are not as apparent include hot surfaces, steam leaks, and boiler blow-down water. Table 6.M.1 shows a number of major sources of industrial waste heat along with the temperature range and characteristics of the source.1 Table 6.M.1 Typical Temperature Range and Characteristics for Industrial Waste Heat Sources1

Sulfidation in a Claus Waste Heat Boiler: A Case Study

ProTreat ® is the best program for my line of work that I could ever imagine. I can find operating problems trusting the ProTreat ® model. ProTreat ® predicts performance amazingly well. ProTreat ® allows us to predict what we would measure the next day after making operating moves. In every case, the plant responded exactly as ProTreat ® had predicted.

Techno-economic Feasibility Study of Acid Gas to Syngas

while the net steam production in the waste heat boiler is reduced. It's partly due to the use of part of the produced steam in the pre-heating section and mostly due to the choice of a different energy recovery method (economizer). Syngas production can largely compensate this reduced steam production though.

A case study of a contract pharmaceutical manufacturing company using an RTO is reviewed to provide a real-world example. This case study Plant has an economizer installed to capture the waste heat from their RTO to pre-heat boiler water. As a contract manufacturer, the waste heat from their RTO is cyclical with production, and the

Feb 22, 2016 · Additionally, there are still more opportunities for recovery in steam generation processes. One typical case is the use of waste heat to preheat air entering the boiler. Optimistically, this can result in a 5% improvement in heat recovery for the system. Another method is the recycle of steam condensate back to the boiler.

Experimental investigation of a liquid desiccant cooling

May 05, 2012 · To obtain sufficient heat to regenerate the liquid desiccant, the existing first-of-its-kind concentric helical coil heat exchanger extracting the waste heat of the boiler needs to be redesigned, and, in particular, the concentric helical coils of the heat exchanger need to be placed inside the chimney to enhance the waste heat extraction.

waste heat boilers and economizers for heat recovery. The gases are, in this manner, cooled down to 473°K and are then quenched with water in a quench vessel directly to bring down the temperature to 417°K and to scrub off the carbon formed (which is around 2% of the feed-stock). The carbon slurry is then separated from the raw gas in a
