Air preheater is designed to increase efficiency of technological process by supplying heated air. An increase in the temperature of the supplied air flow is produced by heat exchange with a gas medium, either smoke, steam, or exhaust gases.
Air preheater is considered to be imperative for modern high power steam boilers. Economizers and air preheaters are also widely used in the mining industry, construction and production. The possible applications of air preheaters is to heat premises and materials.
The OPT air preheater is a heat exchanger of a new generation and an excellent equivalent of traditional boiler air preheaters. The main structural element of the OPT is finned panels with the channels of the heating and heated medium between the panels. The fins position is longitudinal, the flow pattern of gases and air is cross flow.
