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.
