chain grate boiler with fuel of coal gas for steam turbine power plant

Dzl Series Steam Boiler is our company's flagship product. Our company has more than 70 years of accumulation of chain grate boiler with fuel of coal for steam turbine power plant technology, and we have a good understanding of the international market, and we have often reached cooperation with customers in Malaysia, Thailand, Bangladesh, Vietnam, Indonesia, and other regions, basically all Customers who know our company's Dzl Series Steam Boilers will always choose our products because our Dzl Series Steam Boilers are more energy-efficient, safer and more economical. This product is mainly divided into two major series, DZL Packaged Biomass Steam Boiler and DZL Series Coal Fired Chain Grate Boiler.

Textile Mill Coal Fired Boiler Technology

To overcome the steam requirement of the textile processing, textile mill coal fired boiler adopts advanced technology home and abroad and the pilot industry installed 10 ton per hour coal fired boiler to replace carbon intensive furnace oil. Our process heat equipment are used in food processing, chemical, plastic and textile industries.

You must know the problems of energy consumption chain grate boiler with fuel of coal for steam turbine power plant (boiler thermal efficiency) 1, because the thermal efficiency of boiler problems of a high exhaust gas temperature. b sootblowers into low. c ash combustible large. d is too large or too small boiler oxygen. e heat loss is large. f large air preheater air leakage rate. g coarse pulverized coal. h steam - water quality is poor. I defective equipment, operating parameters are forced down. 2, measures to solve the problem of a lower exhaust gas temperature. b timely elimination of soot blowers defects and improve the investment rate of soot blowers. c reduce fuel ash, slag combustibles. d control the amount of oxygen in the boiler. e reduce heat loss. f air preheater to reduce air leakage rate. g qualified coal fineness control. h to improve the quality of soft drinks. i According to circumstances, the boiler heating surface adjustment arrangement. J burner when necessary transformation to fit the gaseous fuel.

Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station chain grate boiler with fuel of coal for steam turbine power plant piping material quality safety risk prevention and control (the "Notice"), to further enhance the quality and safety supervision and management of boiler tubes, effectively preventing security risks, protect the power production safety , as follows.

First, carry out the verification of boiler tubes

The electricity business, special equipment manufacturers to immediately organize boiler tube inspections, to verify whether the focus of the pipe to meet the technical conditions stipulated orders, including the source, size, quantity, quality certificates, raw material procurement contracts, procurement contracts and other piping components. For imported pipe material, but also the verification of the customs declaration, commodity inspection report (proof of entry inspection and quarantine of goods), combined with the production, inspection and testing during use and operation of the situation, in-depth investigation pipe quality boiler safety issues and risks.

Second, effectively prevent security risks

Boiler pipe quality and safety hazards or other problems threatening the security and stability of power station boilers, power companies, special equipment manufacturers to take practical measures immediately, the complete elimination of quality and safety problems; there are significant quality and safety problems, it should stop running generator sets , boiler or stop production and sales of the pipe elements, and replace the boiler pipe complying with relevant standards.

The actual boiler pipe manufacturing unit is unknown or if there are doubts, the relevant information or data can not be traced authenticity, power enterprises, special equipment manufacturers to immediately in accordance with industry standards, inspection and testing institutions have entrusted the appropriate qualifications for boiler tubes were identified test. Test results show that failed boiler or pipe quality does not meet the technical requirements stipulated in the order, power companies, special equipment manufacturers to eliminate hidden dangers in a timely manner or be replaced.

Third, strengthen the source of control boiler pipe

Special equipment manufacturing enterprises, power enterprises should strengthen boiler pipe source control, in strict accordance with the standard provisions of China's relevant laws and regulations and orders technical conditions agreed to carry out boiler pipe design and manufacturing, procurement orders, admission acceptance, inspection and testing, installation and commissioning work, resolutely eliminate substandard or counterfeit boiler pipes enter the field of electricity production; to strictly implement the special equipment safety supervision and management regulations, establish and improve the technical archives and long-term care, to ensure that relevant information can be traced back.

Special equipment manufacturing enterprises, power companies are finding there are significant quality and safety risks of boiler tubes, to report to the local market regulators, power management departments and the National Energy Board sent energy regulators, and to take effective measures to thoroughly rectification to ensure the safe operation of generators . Provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps Market Authority (Hall Commission) should work together with the same level of power management departments, the National Energy Bureau sent energy regulatory agencies and other units, the organization of supervision and inspection, supervision and hidden rectification, effectively preventing security risks.
