The minimum height of the Free-standing Coal-fired Boiler Chimney shall be 8 meters. Only one chimney can be set up in each new coal-fired boiler room. The chimney height shall be based on the total installed capacity of the boiler room and shall be implemented in accordance with the regulations. The chimney height of the oil and gas boiler shall be no less than 8m. If there is a building within a 200m radius around the chimney of a new boiler room, the chimney should be at least 3m higher than the tallest building. If the boiler constructed at different time periods adopts mixed mode to discharge flue gas, and the monitoring position selected can only monitor the concentration of atmospheric pollutants in the mixed flue gas, the most stringent emission limit among the limits of each time period shall be implemented.
Activated carbon is used on different occasions, the corresponding equipment configuration is quite different. At present, dry positive pressure injection technology is used to add activated carbon to waste incineration flue gas treatment, and metering and weighing are used to keep the dosage accurate and controllable. Thus, the on-line detection instrument of waste incineration flue gas can reach the standard stably.
Free-standing Coal-fired Boiler Chimney:
(1) Self-supporting: short construction period, low cost. The disadvantage is that the diameter is large, the wind load is large, the seismic fortification intensity is high should not be used. Therefore, it is mainly used for small diameter, low height chimneys. The height of the self-supporting chimney should not be more than 30m, and the height to diameter ratio should not be more than 10.
(2) Cable type: the height of cable type FRP chimney should not exceed 45m, and its height to diameter ratio (H/D) should not exceed 20.
(3) The characteristics of tower structure is that the steel tower bears the main load of the chimney, including the inner cylinder weight, wind load, earthquake action, and so on, which is similar to the sleeve chimney. Tower chimneys are widely used, ranging from a few meters to more than 100 meters. At present, the height of the glass steel tower chimney has reached 120 meters.
The height of the Free-standing Coal-fired Boiler Chimney
According to the Discharge Standard of Boiler air Pollutants (gb13271-2001), the chimney height of gas, light diesel and kerosene boilers is stipulated. However, the height of the chimney (kerosene) and diesel boiler must not be lower than 8 meters as required by the environmental impact statement.
In urban built-up areas, the use of gas boiler houses for heating and cooling is not restricted. If the exhaust pipe is higher than eight meters, it should work. It is impossible for a large structure like a TV tower to be 300 meters taller even than a TV tower of around 300 meters.
The Free-standing Coal-fired Boiler Chimney is made of stainless steel, FRP and carbon steel.
Hebei Pude Yuelan Environmental Protection Equipment Co., Ltd. is an enterprise engaged in the development and production of industrial chimneys, the company focuses on the development and production of industrial chimneys.
Headquartered in Jingxian Development Zone, Hebei Province, the company has a registered capital of 60 million yuan, covers an area of 9.60000 square meters, of which the building area is 2600 square meters. The main products include self-supporting smoke, sleeve smoke, tower chimney, east smoke, cable smoke, stainless steel chimney, glass steel chimney, mobile compressed garbage bin, horizontal compressed garbage station, hook arm transfer truck, butt type garbage truck and dozens of products. The company has 128 employees, including 8 experts and engineers with master's degree or above, 60% of the employees with bachelor's degree or junior college degree, all kinds of technical personnel 26 people, 60 people special personnel, the company has a number of domestic offices and after-sales service institutions, can provide technical support and product services at any time.
The company's production equipment advanced, strong technical force. Has more than 50 sets of domestic advanced production equipment, including foreign, domestic CNC production lines 6; Hot-dip galvanizing adopts the galvanizing technology and process of Gimeco Company in Italy, and its technical level and production capacity are at the advanced level in China.
After years of development in chimney and municipal waste treatment equipment industry, the company has become a well-known brand in the industry. Through the cooperation with domestic and international design institutes, colleges and enterprises to continuously improve the enterprise's scientific research and development ability. And has cooperated with many universities and reached strategic cooperation with petrochina, Sinopec, Huadian, Huaneng and other enterprises.
In recent years, in order to solve the problem of large-caliber smoke, the company has established a technical cooperation relationship with Beijing Jiaotong University, and invested a lot of manpower and material resources to develop the "precast factory, on-site construction" steel corrugated chimney and urban waste environmental treatment products. At present, the pipe diameter range of the company's products is 0.5m-20m, and the annual production capacity is 660,000 meters.
The company always adhere to the "quality, user" of the enterprise purpose, do not ask for the number of projects, just do the project to make good quality principle, products have been promoted in the project use. Today, the company's products still maintain zero defects, zero complaints, zero accidents, by the owners, construction units of the consistent praise, and establish a long-term cooperative relationship.
