EIA - Greenhouse Gas Emissions Overview

Springfield, Virginia 22161. -------f ABSTRACT Fuel additives have been used, or proposed for use, to serve a variety of functions in combustion systems. This report covers a state-of-the-art review of combustion-type fuel additives as to their potential in reducing air-pollutant emissions for oil and coal firing.

Safety of Oil-Fired Boiler Installations and Oil Storage Tanks. The installation and operation of oil-fired systems must be safe. It is also important that oil is safely stored. The Oil Firing Technical Association (OFTEC) was launched in April 1991 to construct a framework within which oil firing in the United Kingdom and Republic Of Ireland

The ABCs of CHP - Greenhouse Canada

Selective Catalyst Reducer (SCR) A GESi Selective Catalytic Reduction (SCR) is an active emissions control technology system that injects a liquid-reductant (or Diesel Exhaust Fluid - DEF) agent through a special catalyst into the exhaust stream of a diesel engine. The DEF sets off a chemical reaction that converts nitrogen oxides (NOx) into nitrogen, water and tiny amounts of carbon dioxide

Low mass, extruded electrically heated catalysts (EHC) followed directly by a light-off and main converter reduced cold start non-methane hydrocarbons (NMHC) by greater than 80 percent. These reductions were demonstrated on several vehicle

Nonmethane Hydrocarbon - an overview | ScienceDirect Topics

Dec 01, 2010 · Reactive non-methane hydrocarbons (NMHCs) are known to generate tropospheric ozone through atmospheric chemical reactions related with nitrogen oxides (NO x) and radicals under relatively high NO x concentrations (Blacet, 1952, Finlayson-Pitts and Pitts, 2000). Tropospheric ozone is considerably toxic and a strong greenhouse gas.

Dec 09, 2014 · The principle of CHP is simple: a diesel or gas-fuelled engine drives an electrical generator, producing the required electrical power. Meanwhile, heat is recovered from four sources: the engine's jacket cooling, the lube oil, the intercooler, and the exhaust gas. In total, cogeneration can typically recover 95 per cent of the produced heat
