CONDUCTION

What is the transport of heat within a gas or liquid caused by the actual flow of the material itself

CONVECTION

the transmission of electromagnetic rays through space.Radiation Heaters that release all of the heat generated by the flame (and the emissions that result) directly into the heated area Direct-fired heaters What are the most common type of heater found at construction sites?Direct-fired heaters The flame of this heater is enclosed in a heat exchanger that separates combustion products from the air to be heated.Indirect-Fired Heaters When may portable oil-fueled space heaters be stored, handled and used at construction sites only during the heating season (October 15th - May 30th).

A fail-safe system or other approved device, equipment or system designed to shut off flow caused by a rupture in a pressurized piping system.

EXCESS FLOW CONTROL
