hot water heating boiler for residential
Porous materials have always been the main sound absorbing material, such as glass wool. The structural feature of porous sound absorbing materials is that there are many small gaps in the material. When sound waves are incident on the surface of the porous material, they can enter the pores, causing vibration of the air and material within the pores. The friction and viscous action of the air converts the kinetic energy (sound energy) of the vibration into heat energy, thereby attenuating the sound waves. The experiment proves that the sound absorbing material has better absorption for medium and high frequency, and the low frequency absorption performance is poor. Fangkuai Boiler uses a sound-absorbing technology combined with a porous material, and uses a sound-absorbing panel and a muffler chimney to effectively reduce the noise generated during hot water heating boiler for residential operation.
WNS series condensing gas hot water heating boiler for residential, which is very energy-saving effect is prominent feature of saving two devices arranged on the boiler, are ND steel, energy-saving effect, low exhaust gas temperature employed.
1149, what are the relevant personnel requirements and different hot water heating boiler for residential pressure and temperature Description: The boiler of this important site of learning products, the following will continue its work to learn, because this is all hope, this can be a better understanding and about this site products and increase their expertise. So, since good for us, then, what reason not to be taken seriously and conduct it, rather than wasted such a good learning opportunity. 1.10 tons of boiler, its consumption of natural gas per hour, how much is? In addition, different boiler, it is equipped with auxiliary, it is the same as you? 10 tons of boiler, which is on the calorific value, the equivalent of 6 million kcal. Therefore, if the natural gas heating value is calculated according to 8600 kcal, then, an amount of gas consumed per hour, is about 700 cubic meters. And on the issue of two, whose answer is NO, that is, different boiler, it is equipped with auxiliary, it is not the same.
Qinhuangdao City Funing District Branch of Ecological Environment Agency organized the key enterprises responsible person within the jurisdiction of the hot water heating boiler for residential demolition, renovation work will hold a special schedule. The meeting stressed the need to vigorously promote coal-fired, gas-fired boiler demolition, renovation work progress, continued to improve ambient air quality.
At the meeting, staff of the Office of atmospheric area of the current coal-fired, gas-fired boiler demolition, renovation progress has been informed. Up to now, boiler demolition and reconstruction of the region involved all disabled.
First, Funing District compressed air quality improvement increasingly smaller space, air pollution prevention and control situation is very serious, involving various enterprises must attach great importance to effectively assume responsibility for environmental protection.
Second, the coal-fired boiler in accordance with the "water power, chimney down, shifting the body" standard transformation and low nitrogen oxides emissions analyzer mounted nitrogen gas boiler work requirements, make sure the end of this completed, the embodiment late cut-off regulation.
Third, the Bureau of atmospheric sciences, environmental law enforcement unit to further strengthen law enforcement and inspection and supervision, the monitoring center to provide scientific data monitoring, to crack down on environmental violations, it is important to ensure that coal-fired, gas-fired boiler demolition, renovation work is completed on time.
