Glossary

See baghouse.

(1) a collection of integrated devices designed to accomplish a single specific purpose, e.g., an incinerator for the destruction of wastes with its associated waste storage and wastewater treatment, or a production plant for the manufacture of a specific chemical;
(2) a series of interconnecting processes designed to complement each other, e.g., hazardous waste management integrating incineration, wastewater treatment, and landfill;
(3) a group of different process plants at a single physical location or site.

A mechanical device that moves air and creates static pressure.

A machine for driving a blast of air or a fan used to force air under pressure.

A fan is a piece of equipment that consists of a bladed rotor or impeller, located in a housing, and designed to collect and redirect the air or gas by adding sufficient energy to the medium to initiate motion and overcome resistance to the flow.

A curve relating pressure and volume flow rate of a given fan at a fixed fan speed (rpm).

Relationships that describe theoretical, mutual performance changes in pressure, flow rate, rpm of the fan, horsepower, density of air, fan size, and sound power.

Fan performance curve refers to the constant speed performance curve. This is a graphical presentation of static or total pressure and power input over a range of air volume flow rate at a stated inlet density and fan speed. It may include static and mechanical efficiency curves. The range of air volume flow rate which is covered generally extends from shutoff (zero air volume flow rate) to free delivery (zero fan static pressure). The pressure curves are generally referred to as the pressure-volume curves.

The pressure added to the system by the fan. It equals the sum of pressure losses in the system minus the velocity pressure in the air at the fan inlet.

From the moment when the goods are placed alongside the ship, the quay or on a barge, the buyer must bear all the costs and risks of loss or damage incurred by the goods (see Incoterms).

The seller transports the goods from his place of business, clears the goods for export and places them alongside the vessel at the port of export, where the risk of loss shifts to the buyer. The buyer is responsible for loading the goods onto the vessel (unless specified otherwise) and for paying all costs involved in shipping the goods to the final destination.

Faults are the errors or operating problems detected by the controller.

A device to remove solid material from a fluid.

The efficiency of various filters can be established on the basis of entrapped particles; i.e., collection efficiency, or on the basis of particles passed through the filter, i.e., penetration efficiency.

The phenomenon of combustion manifested in light, flame and heat. It may involve:
(1) constructive burning of a raw material for purposes of synthesizing a final product;
(2) constructive burning of a fuel for purposes of releasing usable energy;
or (3) destructive burning of a waste for purposes of destroying specific constituent(s).

A fixed asset generally includes the land, building, and equipment / machinery that are likely to have a useful life to the company for more than one year.

This is a cost your business pays that remains unchanged, whatever your level of sales, for example, the company's monthly rent.

Securities that generate a predictable stream of interest or dividend income, such as bonds, debentures and preferred shares.

A type of loan in which the interest rate does not change during the term of the loan.

A body of gas or vapour that gives off energy, usually in the form of light and heat, as a result of rapid chemical reaction between a combustible material and air, oxygen, or other oxidizing agent. It may be luminous, yellow, and smoky if it contains suspended and incandescent particles (as of carbon soot in the case of a candle), or essentially colourless (natural gas or alcohol flames).

The lowest temperature at which a liquid gives off enough vapour to form an ignitable mixture and burn when a source of ignition (sparks, open flames, etc. ) is present. Two tests are used to determine the flash point: open cup and closed cup.

A device for measuring rate of flow of fluid in a pipeline or channel in either volumetric an gravimetric units.

A passage for smoke and fumes from a boiler/fire etc. in a chimney.

The mixture of gases resulting from combustion and other reactions in a furnace, passing through the smoke flue.

Channel for flue gases in a chimney.

Gas, vapour, or liquid.

The seller (exporter) is responsible for delivering the goods from his place of business and loading them onto the vessel of at the port of export as well as clearing customs in the country of export. As soon as the goods cross the “ships-rails” (the ship’s threshold) the risk of loss transfers to the buyer (importer). The buyer must pay for all transportation and insurance costs from that point, and must clear customs in the country of import. An FOB transaction will read “FOB, port of export”. For example, assuming the port of export is Boston, an FOB transaction would read “FOB Boston”. If CIF is the Customs valuation basis, international freight and insurance must be added to the FOB value.

Maritime bill of sale in which the exporter agrees to a price including the value of the goods and the pre-shipment charges until loading aboard the ship indicated by the buyer.

Forced draft fans are located before the air heater inlet. They move air temperatures ranging from ambient to 200 degrees Fahrenheit (F), depending on where the steam coil air heater is located (before or after the FD fan). Most often, the FD fan is located before the steam coil air pre-heater and will not require any thermal insulation for personnel protection, but may require acoustical sound and noise protection.

Common indoor pollutant deriving from construction materials containing binding resin. Recommended levels less than 0.1 ppm.
Irritant.

Usually refers to air of unacceptable quality where the contaminants are malodorous.

A measure of air velocity in feet per minute (Feet per minute, Foot per minute).

Foot per second.

Standardized motor mounting and shaft dimensions as established by NEMA (National Electrical Manufacturers Association) or IEC (International Electrotechnical Commission).

Free field refers to any wide-open area or space that has nothing around to reflect or interfere with sound in any direction.

A zone of the port in which the goods can be legally discharged and stored, without paying customs duties and waiting for their re-exportation or their sale in this country.

Port designated by the government as a duty free zone for the not prohibited goods. These goods can be stored, "dispatched", used in the manufacturing process, etc… within the limits of this zone and then re-exported without paying any duties. But, some fees and duties should be paid on these goods or on the products manufactured from these goods, if these goods pass from the free zone to a zone which is subject to Customs Authority. The free zone is also called “Zone of Foreign trade”.

Cost of transport.

Freight designates the cost of transport of the goods, but also the cargo transported (which gives rise to the payment of freight) and the price of hiring in the event of chartering a ship.

Chlorinated hydrocarbon used as refrigerants and aerosol propellants. Common indoor pollutants. Non-toxic.

The number of oscillations or cycles per unit of time. Acoustical frequency is usually expressed in units of Hertz (Hz) where one Hz is equal to one cycle per second.

Foot.

Foot pound.

Feet per minute.

Feet per second; also written ft/sec.

Square feet.

Cubic feet.

Cubic feet per hour.

Cubic feet per minute.

Cubic feet per second.

A substance used to produce heat or power upon combustion in an incinerator, boiler, or other type of energy recovery device. It may be naturally derived (e.g., natural gas, fuel oil, coal) or waste-derived (e.g., refuse, discarded materials, process residuals, etc).

Line current (amperage) drawn by a motor when operating at rated load and voltage on motor nameplate. Important for proper wire size selection, and motor starter or drive selection. Also called full load current.

The Full-Load Torque is the torque required to produce the rated power of the electrical motor at full-load speed.

Airborne solid particles usually less than 1 micrometer (um) in size formed by condensation of vapours, sublimation, distillation, calcination, or chemical reaction.

A piece of metal, connected in the circuit to be protected, that melts and interrupts the circuit when excess current flows.
