Cost-Effective NOx Control for Air-Preheated Systems
New advancements in combustion control technologies, such as flue gas recirculation (FGR) and low NOx burners (LNB), have made it possible to achieve ultra low NOx levels without using expensive post-combustion flue gas clean-up technology. For some natural draft units it may be possible to meet the most stringent of the NOx regulations with cost-effective combustion control technologies. For ...

Pressurised pulverised coal combustion ? a coal-based combined-cycle state of the cooperative project: cleaned flue gas matches specifications for use with gas turbines
A high efficiency of 60% in a combined-cycle power plant technology with fuels like gas or light oil is estimated to be achievable. On the other hand existing conventional coal-fired power plants based on steam generation have an efficiency of about 40?45%. A huge potential of improvement in efficiency could be achieved by the implementation of a simple and cost-effective technology: PPCC, a ...

Removal of ecologically harmful pyrolysis gas and vapours
Type HOFGAS®- IFM4c/1000 Commissioning August 2002 Site Waste water treatment plants Situation As a result of new authority requirements, Romag AG set up operation of a plant for the drying and gasification of wastewater sludge. Drying vapours are formed during the sludge drying and pyrolysis gas during gasification. These emissions must be burned in an ecological way, in compliance ...

A STIEFEL project KVA Linthgebiet Niederurnen case study
The waste incineration plant KVA Linthgebiet is situated in Switzerland. The plant disposes of a total of 120’000 tons of waste each year from 240‘000 inhabitants in the surrounding area. Due to the thermal recovery, it produces annually 84 GWhour of electrical energy and therefore saves 250’000 litres of fuel oil by providing energy to a district heating system. Background and ...

The Other Side of Zirconium Oxide case study
Regular Fuel Efficiency Applications Separate Oxygen and Combustibles Sensors In standard flue gas applications for Thermox analyzers, the user generally tries to extract the maximum energy from the fuel and transfers as much of that energy as possible to the process. These applications require the process to be operated as efficiently as possible by keeping both oxygen (excess air) and ...

Low emissions from large plants too
Type HOFGAS®- LPM 3000 Performance 3’000 Nm³/h, 15’000 kW Location Scotland (GB) SituationEvery year, 150’000 tonnes of waste from Edinburgh, Lothian and the Borders Region are brought to the Dunbar landfill site. The waste is transported by rail to the site. In 2002, the UK Environmental Agency (EA) introduced the strictest emission regulations in Europe. The flue gases are not ...

Performance of the low-emission flare
Job report / Elbisgraben (Bale / Switzerland) The summer of 1992 had finally arrived. The 5MW low emission furnace in the district heating station Liestal was ignited, supplied with landfill gas from Elbisgraben landfill. Since then the plant has been running continuously and the comprehensive measurements taken, verify that all targets aimed at have been achieved: plant efficiency 90%, low ...
