Fly Ash Treatment – Plasma Torches versus Graphite Electrodes

by Tetronics (International) Ltd  (Aug. 24, 2016)

Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high ...

Utilizing Waste Heat For Power

by ElectraTherm  (Dec. 2, 2014)

Continuous duty gen-sets provide base-load power generation in diverse applications around the globe. However, high fuel costs and engine maintenance are pain points felt by operators.

Is waste heat the silver bullet?

by Energy Efficiency Markets  (Aug. 13, 2009)

The energy industry tends to get stuck on certain words. Silver bullet is one of them. Insiders and policymakers often like to say there is no silver bullet to fix US energy woes. We need a portfolio of solutions – renewables, efficiency, smart grid, transmission expansion, coal sequestration, etc. That may be true, but Tom Casten begs to differ. ...

Exergy or the entropic drive: waste heat and free heat

by Inderscience Publishers  (Jul. 16, 2013)

The dissipation of exergy is conventionally held to be the inference of the entropy growth. In this conventional perspective, the universe is running down towards equilibrium or heat death. Recent cosmological findings of 1998–2000 give empirical evidence that the universe is instead moving away from equilibrium while its entropy increases. We can ...

Recycling industrial waste heat for sustainable district heating: a multi-actor perspective

by Inderscience Publishers  (Mar. 10, 2009)

Addressing the climate change and energy scarcity problems are two of the most complex sustainability challenges facing not only scientists, but also policy makers. Attempts at tackling these issues should be approached from two fronts: by increasing the energy efficiency (demand side) and by promoting the usage of renewables and non-Greenhouse ...

WEISS provides for the heat - and disposes of the waste case study

by WEISS A/S  (Dec. 9, 2011)

The very first time PLIMOB learnt about Weiss was in 1995 at which time contacts at IKEA told about combustion plants from WEISS. IKEA is the most important customer for PLIMOB so the management listened to the recommendations. PLIMOB is producing wood furniture; large quantities of wood chips and sawdust are a spin-off effect from their ...
