A unit of pressure equal to the pressure exerted by a column of liquid water 1 inch high at a temperature of 39.2°F. One inch of water is equal to 0.0735 in. of mercury, or 0.036 psi. Atmospheric pressure at standard conditions is 407 in. w.g.

A unit used in measuring pressures. One inch of water column equals a pressure of 0.25 kPa (0.036 lb per sq in.).

To cause to burn to ashes; to consume by fire; to become completely burned; to destroy a waste by combustion.

An enclosed thermal device in which solid and hazardous wastes are combusted to reduce volume and hazard.

Rules formulated by the International Chamber of Commerce to standardize the business practices, to support the trade and to minimize the risks of incomprehension relating to the commercial terminology. The terms used in the contracts with foreign partners are codified in order to define which part should support the expenses and from which point they are incurred. These terms are usually mentioned in sales contracts, or they are implicitly agreed in accordance with the practices of the international business.

Incoterms (International Commercial terms) International practices created in 1936, defining the rights and obligations of the buyer and seller, with regard to the delivery of the goods sold. The Incoterms 2000, currently applicable, were established by the International Chamber of Commerce (CCI). The goal of the Incoterms is to define the transfer point for risks, the transfer point for expenses, as well as the documents or data to be provided by the seller to the buyer. The principal innovation of the Incoterms 2000 is to address the issue of customs clearance.

The study, examination, and control of air quality related to temperature, humidity, and airborne contaminants.

A device designed to pull combustion air and combustion products through an incinerator and associated air pollution control devices. The facility is operated under a negative pressure (less than atmospheric) to reduce intermittent and fugitive releases.

An ID fan will draw the flue gas out of the boiler through the air heater and air pollution equipment and then exiting up through the stack. The operating temperatures of the ID fans will require thermal insulation for personnel protection and may also require acoustical sound and noise protection.

Induced draft fans (ID fan) are located at or near the stack, and normally move gas temperatures ranging from 350 degrees F to 150 degrees F. Steam-generating boilers designed to operate with a balanced furnace draft or without a forced draft fan require an ID fan. An ID fan will draw the flue gas out of the boiler through the air heater and air pollution equipment and then exiting up through the stack. The operating temperatures of the ID fans will require thermal insulation for personnel protection and may also require acoustical sound and noise protection.

The simplest and most rugged electric motor, it consists of a wound stator and a rotor assembly. The AC induction motor is named because the electric current flowing in its secondary member (the rotor) is induced by the alternating current flowing in its primary member (stator). The power supply is connected only to the stator. The combined electromagnetic effects of the two currents produce the force to create rotation.

Electrical devices made of wound or coiled wire. Current passing through the coil creates a magnetic field that in turn produces mechanical work.

Air leakage inward through cracks and interstices, and through ceilings, floors and walls of a space or building.

That which flows in: specifically fresh air entering through a ventilation inlet.

(1) In motors, classified by maximum allowable operating temperature. NEMA Classifications include: Class A=105°C, Class B=130°C, Class F=155°C and Class H=180°C.

(2) Protection of a room or building from undesirable gains or losses of sound or heat.

The pressure inside a building envelope.

The temperature in an enclosure or occupied space.

An electrically charged atom. An atom that has lost one or more of its electrons is left with a positive electrical charge. Those that have gained one or more extra electrons are left with a negative charge.

The process whereby one or more electrons is removed from a neutral atom by the action of radiation.
