standard boiler feed water temperature

In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water standard boiler feed water temperature to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.

Many Pakistan guests always ask a questions before deal, “what is the difference between SZL series coal fired steam standard boiler feed water temperature and DZL series coal fired steam boiler ?” there are mainly difference between them.

2, the exhaust arrangement (flue gas) heat recovery.

Exhaust heat recovery from the flue gas passage to increase spray tower, heat exchange by spraying water mixed with the flue gas, a large amount of heat carried away by the fumes spray water, reduced exhaust gas temperature, high temperature spray water is pressurized by the circulating pump through a heat exchanger or other heating boiler return mechanisms, in order to achieve recycling of flue gas waste heat of exhaust gas temperature is reduced, saving energy and reducing the running cost and the fuel. Than the exhaust heat recovery economizer much better energy-saving effect, even some devices may be the flue gas water vapor latent heat recovery. But the exhaust heat recovery unit investment, more equipment, additional operating costs also, the failure rate is high. The economizer is simple and reliable, no mechanical component failure rate, operating costs are zero.

There are many advantages of electric standard boiler feed water temperature. It is an economical, energy-saving, safe, scientific, environmental-friendly, emerging, and efficient heating way to increase the number of users of electric boiler. With the combination of electric boiler and ground heating system, room temperature decreases gradually from bottom to top, giving people the feeling of cold feet. Improve blood circulation, promote new town metabolism, has a certain health care effect. In line with the "warm from the foot, ten thousand cold at the foot of" the principle of traditional Chinese medicine. Electric boiler work without any odor, noise, no electronic radiation.
