Directing against problems concerning the rate of putting steam air-heater or hot air circulating facility into service is lower than 10%

even being left unused for a long-term

the feasibility of abolishing said facilities has been analysed.It is believed from analysis that the said facilities having never been put into service can be abolished

while the said facilities with rate of putting them into service being lower than 10%

whether to be abolished or not

it is necessary to carry out feasibility study.Abolishing the steam air-heater or hot air circulating facility can make electricity consumption of the air supplying system to be decreased by 5%~10%

the economic benefit is very remarkable.
