Enthalpy Held in Combustion Gas

Enthalpy of Combustion of Microcrystalline Cellulose

A test substance with characteristics and properties similar to those of cellulose· based solid waste products is needed to calibrate calorimeters and combustors which will be routinely burning these materials to determine their calorific values precisely for use in commerce. Microcrystalline cellulose was found to be a good calibrant for this purpose. The enthalpy of combustion of microcrystal...

Enthalpy Calculation for Pressurized Oxy-coal Combustion

Oxy-fuel combustion is recognized one of the most promising available technologies that zero emission accomplishment may be in the offing. With coal burned under the pressure of 6MPa and oxygenenriched conditions, the high temperature and high pressure gaseous combustion product is composed of 95% CO2 and water-vapor, with the rest of O2, N2 and so on. However, once lauded as classic approach o...

Gas Chromatography for Combustion Gas Analysis

A basic discussion of the principles of gas chromatography and a description of a combustion gas analyzer using this chemical analysis techniqlJe are presented. During the past several years the combustion gas analyzer has been used extensively in airbreathing propulsion research projects at the APL Propulsion Research Laboratory to analyze samples from supersonic combustion and fuel-air mixing...

Gas cleaning in flue gas from combustion of biomass

Reformer Gas Application in Combustion Onset Control of HCCI Engine

Homogenous charge compression ignition (HCCI) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. To avoid excessive pressure rise rate and knocking, HCCI engines are fueled with highly diluted mixture using a combination of excess air and/or EGR. HCCI combustion is attractive due to ...
