Pulverized fuel coal burners (typically turbulent air burners, vertical burners, or nozzle burners) receive hot primary air containing the PF and introduce the mixture to secondary air in such a way that it provides a stable flame. The flow rates of both primary and secondary air are controlled by dampers. An ignitor is required to initiate combustion, and the flame front is maintained close to the burner, with the heat of combustion used to ignite incoming PF. A flame safety device electronically scans the flame and initiates corrective action if required.

The heats of combustion used were taken from Kharasch s compilation (Bur. Standards J. Research 2, 359 (1929)) or from Landolt-Bornstein Tables.

The objectives of Aho s study [8] were to investigate the effects of peat type, particle density, diameter and moisture content, and oxygen concentration on the flue gas emissions of nitrogen oxides and sulphur dioxide from a homogenous countercurrent batch bed combustion using a pot furnace. His aim was to simulate the interaction of chemistry between the fuel bed system and the combustion chamber of a overfired batch bed. However, he also presented some results on the combustion heat rate. 

Fluidized-bed combustion uses air-classified municipal solid residues to provide heat for a conventional gas turbine to produce power. Several stages of cyclone separators are also used to remove particulates from the gas prior to its expansion through the turbines. An advantage of the process is reduction of noxious gas emission.

Pfefferle and Lyubovsky executed types of measurements that yielded critical information between active Pd phases for catalytic combustion using pure ot-alumina plates with zero porosity as a support for the catalyst. This procedure uniformly covers the plate with metal particles on the top surface where they are easily available for the reaction gases and optical analysis. This type of experimental procedure has shown that in high-temperature methane oxidation the reduced form of the supported palladium catalyst is more active than the oxidized form. The temperature at which the PdO Pd... 

The cetane number is a measure of fuel combustibility using a variable compression ratio cetane engine. High-cetane-number fuels generally allow for an easier start in cold weather, provide more complete combustion, and yield an overall increase in engine efficiency, primarily power.

High explosive mixtures with potassium and sodium chlorates or potassium and ammonium perchlorate belong to a separate group a mixture of these salts with any combustible used in a suitable quantity will act as an explosive. 

In this paper, we demonstrate how mean maximum reflectance of vitrinite in oil (hereafter referred to as R ) can be used in place of conventional chemical-rank parameters (volatile matter and fixed carbon) to estimate the relative yields of carbonization products, specific properties of gas produced by carbonization, and chemical properties of coal such as calorific value and free swelling index (FS1). Further, we illustrate that measured R can be used to detect coal oxidation, to categorize coals for certain combustion uses, and to help classify coals by rank. 

The scope of the modern science of combustion is significantly broader than it was a few decades ago. Together with the traditional application of combustion in energy installations—to obtain mechanical work, heat, electrical energy, and to maintain transportation systems, etc.—new applications have been developed such as the production of new materials through combustion, use as a source of information about chemical kinetics at high temperatures and pressures, and the production of a high-temperature, laser-active medium.

Perchloric acid spilled on the floor or bench top represents a hazard. It should not be mopped up, nor dry combustibles used to soak up the acid. The spilled acid should first be neutralized and then soaked up with rags or paper towels. The contaminated rags and paper towels must be kept wet to prevent combustion upon drying. They should be placed in a plastic bag and sealed and then placed in a flammable waste disposal can. If the spill can be rinsed down a chemical drain, neutralization of the wetted area is recommended, followed by additional rinsing.16,30,31... 

The cleaned coal was dried at 110 C overnight and then sampled for analysis. Moisture, ash, and pyritic and sulfate sulfur were determined by ASTM procedures (11). Total sulfur was determined by high-temperature combustion using a Fisher Total Sulfur Analyzer. Organic sulfur was determined by difference.
