Pressure above zero pressure the sum of the gage and atmospheric pressures. A cubic foot referring to the actual temperature and pressure of the gas. Usually abbreviated ACF ACTUAL VOLUME The volume of a gas at its actual temperature and pressure. In the U.S. this is normally expressed as actual cubic feet. ACTUATING SIGNAL ADIABATIC TEMPERATURE A signal which causes a control element to function or position itself accordingly. The theoretical temperature that would be attained by the products of combustion provided the entire chemical energy of the fuel the sensible heat content of the fuel and combustion air above the datum temperature were transferred to the products of combustion. This assumes 1. Combustion is complete. 2. There is no heat loss. 3. There is no dissociation of the gaseous compounds. 4. Inert gases play no part in the reaction. AERATION AFTERBURNER AFTERCOOLER To circulate oxygen through a substance. An air pollution control device that removes undesirable organic gases by incineration. A device used for lowering the temperature of a fluid. Typically used on air compressors or to reduce the temperature of boiler blow-off discharge before it enters the building drain. AGGLOMERATING MR ATOMSIZING OIL BURNER A caking characteristic of a coal. A burner for firing oil in which the oil is atomized by compressed air which is forced into and through one or more streams of oil breaking the oil into a fine spray. AIR BLAST AIR-COOLED WALL AIR DEFICIENCY The flow of air at a high velocity usually for a short period. A refractory wall of hollow construction through which air passes. Insufficient air in an air-fuel mixture to supply the oxygen theoretically required for complete combusion of the fuel. AIR DRIED Condition of coal after sample has been exposed to 85F to 95F air until weight is constant. AIR-FUEL RATIO AIR INFILTRATION AIR MOISTURE
