Combustion of fuels - Products and effects of combustion

Incomplete combustion occurs when there isn't enough oxygen to allow the fuel to react completely with the oxygen to produce carbon dioxide and water, and also when the combustion is quenched by a heat sink such as a solid surface or flame trap. From: Handbook of Industrial Hydrocarbon Processes, 2011

Fuels and Combustion - BrainKart

During complete combustion carbon and hydrogen combine with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). During incomplete combustion part of the carbon is not completely oxidized producing soot or carbon monoxide (CO). Incomplete combustion uses fuel inefficiently and the carbon monoxide produced is a health hazard.

Wood Combustion Basics - Masaryk University

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

safety advice – Solid Fuel Association

Ideally, combustion breaks down the molecular structure of the fuel; the carbon oxidizes to carbondioxide (CO 2) and the hydrogen to water vapour(H 2 O). But an incomplete process creates undesirable and dangerous products. To ensure complete combustion, even modern equipment with many features must operate with excess air.

Incomplete Combustion - an overview | ScienceDirect Topics

May 01, 2000 · Unburned carbon is also found in the ash removed from solid-fuel firing. Sometimes referred to as LOI (loss on ignition), the combustibles content of ash is used to describe incomplete combustion in coal- and solid-fuel fired boilers. A solid-fuel fired installation I worked on in the late 1980's had considerable carbon content in the flyash during startup. Burner modifications changed the black dirty ash …
