Wort boiling consumed 50% of heat energy in a brewery,and reuse of secondary steam was important in helping business to make great profits.

Based on the practices,the characteristics,the uses of secondary steam,and the problem that should be paid attention to in the design for the steam recycled are presented in the article.

A new type of plate heat exchanger using low-pressure secondary steam was introduced in this article.

By chosing the high quality and pressed inversed-barrel steam trap,the steam-drive pump,suitable steam flash tower and pipeline,the discharged steam condensate water and its second steam are reused;By comparing the quality and price of the steam trap,the huge adavantage in energe-saving is observed.

Energy Saving and Surplus heat use in steam heating system;

This paper describes the innovation on hydrogen generator by ammonia decomposition process , electric heating is replaced by steam heating , the vaporizer of ammonia is reconstructed, nitrogen is heated directly by electric heating to make molecular sieve regenerate, purification system is transformed .

This paper analyses the water-film formation in steam heating roller and its influence on heat conduction performance to roller, and then provides a better settlement scheme for the problem of how to eliminate the water-film and improve the heat conduction performance of the roller.

Methods Respective analysis of 169 cases of artificial airway humidification,48 cases of heating vapor humidification,42 cases of dripping humidification,89 cases of combined.
