Steam trap in the steam heating system plays a role in exhaust emissions, in the selection of appropriate steam trap can make the steam heating equipment to achieve the highest efficiency. To achieve the optimization effect, we must have a comprehensive understanding of the performance and characteristics of various types of trap. Steam trap variety, performance is different. The choice of steam trap, should first choose their own identity, in order to best meet the steam heating equipment operation before considering other objective conditions, such choice needs steam trap is correct and effective.

steam traps to be "identified" steam and condensed water can play a role in blocking air drainage. "identification" and the condensed steam water based on three principles : the poor density, and temperature difference of change. So on the basis of three principles of creating three types of steam traps : classified as mechanical type, thermal static type, thermal power-based. 1.
