Fuel oil means heavy distillates or residues from crude oil or blends of such materials intended for use as a fuel for the production of heat or power of a quality equivalent to the “American Society for Testing and Materials’ Specification for Number Four Fuel Oil (Designation D 396-69)”, or heavier.
heat pump means a machine, a device or installation that transfers heat from natural surroundings such as air, water or ground to buildings or industrial applications by reversing the natural flow of heat such that it flows from a lower to a higher temperature. For reversible heat pumps, it may also move heat from the building to the natural surroundings;
Fuel cell means an energy converter transforming chemical energy (input) into electrical energy (output) or vice versa.
Fuel means any solid, liquid or gaseous combustible material;
Hydraulic lift tank means a tank holding hydraulic fluid for a closed-loop mechanical system that uses compressed air or hydraulic fluid to operate lifts, elevators, and other similar devices.
Flex fuel vehicle means a vehicle with one fuel storage system that can run on different mixtures of two or more fuels.
Fuel Additive means any substance designed to be added to fuel or fuel systems or other engine-related engine systems such that it is present in-cylinder during combustion and has any of the following effects: decreased emissions, improved fuel economy, increased performance of the engine; or assists diesel emission control strategies in decreasing emissions, or improving fuel economy or increasing performance of the engine.
Tank means an enclosed space which is formed by the permanent structure of a ship and which is designed for the carriage of liquid in bulk.
Finished water means the water that is introduced into the distribution system of a public water system and is intended for distribution and consumption without further treatment, except as treatment necessary to maintain water quality in the distribution system (e.g., booster disinfection, addition of corrosion control chemicals).
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Supply Pipe means any part of a service pipe which a water undertaker could not be, or have been required to lay under section 46 of the Water Industry Act 1991; and
Compression Ignition Engine means an internal combustion engine with operating characteristics significantly similar to the theoretical diesel combustion cycle. The regulation of power by controlling fuel supply in lieu of a throttle is indicative of a compression ignition engine.
Combustion turbine means an enclosed fossil or other fuel-fired device that is comprised of a compressor, a combustor, and a turbine, and in which the flue gas resulting from the combustion of fuel in the combustor passes through the turbine, rotating the turbine.
Fuel burning equipment means any furnace, boiler, apparatus, stack and all associated equipment, used in the process of burning fuel.
Flue means a passage for conveying the products of combustion from a gas appliance to the external air.
