ce approved coal dhl boiler

The third reason is that the amount of nitrogen oxide released during operation is very small. Most heating equipment such as ordinary ce approved coal dhl boilers need to use coal materials as raw materials when they are in operation. Materials such as coal generally release a large amount of hazardous air-quality substances when burned. The condensing boiler uses the steam produced by natural gas combustion as the raw material when it is in operation, so the nitrogen oxide content released during the operation is much lower than the prescribed standard. The analysis of the reason for the year-by-year increase in the sales of condensing boilers has come to an end for the time being.

A general increase in the standard of environmental governance, Huzhou City, Zhejiang Province closely follow the direction of development policy, will gradually phase out coal-fired ce approved coal dhl boilers or adapted for the gas boiler. According to statistics, Huzhou City Nanxun five years has eliminated nearly 3,000 small coal-fired boiler, saving 720,000 tons of coal resources.

Remediation process, district departments form a joint working group, while the seizure of small boilers, while helping business transformation. Behind the small boiler one Taiwan "puff", representing a small wood processing, printing and dyeing, textile and a number of high pollution and high energy consumption enterprises. They only destroyed the visual landscape, but also pollutes the lies to be the region's transformation and upgrading process must break the "pots and pans."

Huzhou referred morning Decoration Co., the person in charge mentioned: "In the past coal-fired boiler pollution does not say, but heating is not stable, press only a day after more than 300 wood boiler replacement, productivity improved significantly, now at least a day. can be pressed more than 500. "this shows once production efficiency improvement, enterprise back to the speed can be increased to a year.

After the disappearance of small boilers, or to benefit a lot of people around. "Our village is known for the production and processing of small wood gathering, the family opened the window every morning before'll see a row of chimneys in the distance 'spit black smoke'. Now grinding temperature, steam generator replaced the original coal boiler, surrounding environment has improved significantly. "FEATURE before the flood who lives in the village of Lao Shi sincerely laments.

Improvement in the area of ​​active removal of small boilers companies subsidies, also made detailed provisions on subsidy amount of different types of boilers. Meanwhile, the district has built South Lake thermoelectric, thermoelectric GCL, Guodian three cogeneration projects, the laying of 200 km of heating pipe network, and the end of last year to achieve full coverage of central heating.

BOILERS deposited combustible material, such as carbon black, oils idle, coal, etc., it is mainly due to incomplete combustion of the tail into the ce approved coal dhl boiler. Especially when the ignition and shutdown, most likely to cause incomplete combustion, the rear of the boiler deposited a large amount of combustible material. These deposits reduce the heat transfer surface of the tail heating the exhaust gas temperature rises. When the exhaust gas temperature rises to a certain value, there is sufficient oxygen combustion condition occurs at the secondary combustion, secondary combustion is in the shutdown some minutes or hours after the occurrence, which is the ignition point of combustible material and heat conditions. Running faster flow of the flue boiler, heat of the combustible substances produced smoke away quickly, only a slow oxidative, ignition combustion can not be achieved. After the shutdown, the gas flue, the flow is stopped, the heat generated by the oxidation of combustible material not easily lost, the temperature will rise. If the door or flue damper closed tightly, leakage into the fresh air for combustion, causing secondary combustion after shutdown.

When coal-fired ce approved coal dhl boilers, coal-fired boilers need to use technological innovation to promote energy conservation and environmental protection is an important step in the process of our country, many cities are very encouraged coal-fired boiler reconstruction project, giving premium policy, depending on the duration and scale of reform. So when coal-fired boiler, which are more commonly used technology? Following on from the transformation of high-quality brand of coal-fired boilers - fast boiler party, to present to you. 1, coal-fired boiler auxiliary blowers and energy-saving technologies induced draft fan energy consumption and thermal efficiency of coal-fired boiler operation parameters directly related, appropriate conversion technology can be used for coal-fired boiler, the boiler load in accordance with the transformation requires adjusting drum, the air volume to maintain optimum conditions of operation of the boiler, the boiler can save not only coal, but also reduce the power consumption of the fan, so that to achieve a better energy-saving effect. 2, the transformation of coal fired boiler technology devices are currently grate-fired boilers burning coal, which accounts for the majority of coal-fired boilers in the coal boiler will hinder into the wind, affecting the combustion. When the coal-fired boiler coal bucket coal transformation component layer, using gravity filters to block coal, coal bottom-end loosely distributed on the grate, the air inlet beneficial, to improve combustion, improve coal combustion rate, reduce ash carbon content. 3, combustion coal-fired boilers by the transformation technique of this technique coal-fired boilers, pulverized coal amount to be injected into the furnace in place, so that the combustion grate base layer, an appropriate amount of suspension firing increases, must be obtained the saving rate. As for boiler fuel, gas type, you can replace the old with the new energy-saving burner, behind the burner to be transformed. These are more commonly used in coal-fired boilers to several techniques, since each technique is suitable for different types of coal-fired boilers, so companies want to transform the existing boiler, then they would have to consult the excellent quality of the coal-fired boiler company and then consider and select an energy-saving effect is most obvious, to maximize the advantages of technological transformation of coal-fired boilers.
