Recently, the letters and the ecological environment unit, the letter of "boiler air pollutant emission standards" in the "gas boiler exhaust pipe predetermined height of not less than 8 meters, within 200 meters from the building around the radius of the new boiler room chimney when was the tallest building in which the chimney should be higher than 3 meters "requirement questions.
First, the new urban gas boiler chimney should be performed outside the specified height is 3 meters above the surrounding buildings (there are many communities within 200 meters around the building height higher)?
Second, on the 20t / h steam boiler and above, and more than 14MW hot water boiler to be installed pollution-line monitoring equipment, this means that a single 14MW boiler or boiler means the total audience of 14MW?
Third, for example, I have more than 2MW heating station natural gas hot water boiler 7 units, exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment?
A "boiler air pollutant emission standards" (GB13271-2014) states that "fuel, gas boiler stack height of not less than 8 m, particularly boiler stack height is determined by the EIA document approved. Chimney around the new boiler room when there is a building within a radius of 200 meters, the tallest building in which the chimney should be higher than 3 meters. when there is a building within 200 meters around the new boiler house chimney radius, "according to the provisions in the new urban area gas boiler should be implemented", the chimney should be higher than the provisions of the tallest buildings in more than 3 meters, "the.
Two, 20t / h steam boiler and above, 14MW and more hot water boiler must be installed in the line monitoring apparatus contaminants "14MW and more hot water boiler" means a single boiler.
Third, on the "exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment" problem, according to "People's Republic of China Air Pollution Prevention Law" Article 24 "key sewage units should be installed, using air pollutant emissions automatic monitoring equipment, and environmental protection departments to monitor network devices, monitoring equipment to ensure the normal operation of public and emissions information in accordance with law. "provisions, as well as the" State Council on the issuance of three-year action plan to win the blue sky to defend the notice "(Guo Fa [2018 ] No. 22) "outfall height of over 45 meters of elevated source, as well as petrochemicals, chemicals, packaging, printing, painting and other VOCs emissions from industrial sources focus, the focus of sewage into the Directory of key areas should be basically completed by the end of 2019 to install flue gas automatic monitoring facilities, the country should be basically completed by the end of 2020 the automatic installation of flue gas monitoring facilities. "requirements, if the exhaust pipe where the company was listed as key units of sewage, flue gas monitoring facilities should be installed automatically, otherwise, no installation.

How to choose the industrial boilers metallurgy, chemical industry, food processing and other industries to be able to reach a certain temperature conditions in the manufacturing process, often using some high-quality industrial boilers as heating equipment, while these devices are running stability and security, and even environmental protection and durability have attracted wide attention of enterprises. So for businesses, how can you choose a high-quality industrial boiler? First, choose a reliable quality and reliable industrial boiler boiler quality means the material itself to be able to withstand any environment, which requires materials selected industrial boiler itself up to a certain level. Currently more excellent steam industrial boilers are made of forged 360Ti stainless steel, the process comprising heating in a good corrosion resistance can be maintained long-term continuous stable operation under the heating condition. Secondly, we must choose the water capacity of the large industrial boilers due to industrial production processes require continuous heating, industrial boilers required to have their own characteristics have a steady heating. Select the water capacity of the large industrial boilers can ensure the water level inside the small fluctuations in industrial boilers, heat exchangers makes the whole device more fully, the heat transfer efficiency will be higher. And this business can get the appropriate information according to the product manual or consult the manufacturer. In addition, the modular design of the boiler can select some of the more current quality of Beijing has been able to achieve industrial boilers modular design, industrial boilers either stand-alone modular and can be freely combined, means for the user to be more mobile and flexible operational in terms of maintenance and repair, also more convenient, not only greatly improve the utilization of industrial boiler system also greatly reduces the costs. It can be said, choose a high-quality industrial boilers for enterprises is to choose a more efficient and stable work, and this heating equipment for businesses also means lower maintenance costs, improve the overall their overall efficiency in the heating process. Of course, the purchase price and other factors are also screening elements of industrial boilers, companies can pay more based on the actual selection of heating and environmental conditions.
Sewage is very important in a steam boiler, and the effect is very obvious, whether periodic or continuous sewage discharge can effectively discharge excess boiler water salinity. But in hot water boiler blowdown effect is not very obvious. The difference is that: first steam boiler into the water only 10 tons per hour, while the same hot water boiler capacity per hour into the water about 240 tons. It can be seen in the hot water boiler traffic is particularly heavy, is more than 20 times the capacity of the same steam boiler.

The steam pressure in the boiler is regulated by the Boiler Operator. This is a pressure control which senses the steam pressure and turns the boiler on and off accordingly. This control must be operationally tested. Adjust the pressure setting on the control to a pressure less than the boiler pressure (as shown on the boiler pressure gauge).Learn More

Boilers are blown up every year as a result of poor atomization of oil which results in incomplete combustion and can lead to unburned oil puddling on the floor of the furnace. To prevent this, the oil tips must be clean, the oil temperature must be correct, the oil viscosity must be in spec, and the atomizing steam (or air) pressure and fuel oil pressure must be properly adjusted.Learn More
