Carbon kiln waste heat boiler

Working principle

Zhengguo's carbon waste heat utilization technology mainly includes two series of natural circulation water tube waste heat boilers: carbon rotary kiln waste heat boilers and tank type carbon waste heat boilers. Adopting a vertical inverted II structure. Its furnace structure has a novel layout, advanced performance, and is the first of its kind in the country. Compared with the traditional carbon kiln waste heat boiler, it occupies a small area and saves civil construction investment; Novel structure and superior performance; Being at the forefront of domestic standards is a new milestone in the development of carbon waste heat boilers.

Carbon waste heat boilers mainly include two series of natural circulation water tube waste heat boilers: carbon rotary kiln waste heat boilers and tank type carbon waste heat boilers. This furnace adopts a vertical inverted II structure, with a novel furnace layout and advanced performance, which is the first of its kind in China.

The use of high-temperature flue gas generated by carbon kilns for waste heat power generation is the first of its kind in the domestic carbon industry. It not only explores a new path for the utilization of waste heat from large capacity carbon kilns, fills a gap in China, but also generates good economic benefits.

Performance characteristics

1. The carbon kiln waste heat boiler is vertically arranged, and the components are compact. Compared with the traditional carbon kiln waste heat boiler, it occupies a small area and saves civil construction investment; Novel structure and superior performance; For the leading level in China, it is a new milestone in the development of carbon waste heat boilers.

2. This furnace adopts a steel tube type economizer, which has high mechanical strength, shock resistance (due to the large fluctuation of flue gas in the waste heat boiler, it is easy to cause shock to the water vaporization of the economizer), strong load adaptability, and easy system layout and operation.

3. The boiler adopts a membrane water-cooled wall structure, which has high heat transfer efficiency and good sealing performance, solving the disadvantages of traditional boilers such as large air leakage, high heat dissipation loss, and high system energy consumption.

4. The boiler adopts the principle of inertial separation to achieve two-stage gas solid separation inside the furnace, which solves the disadvantages of traditional boilers relying solely on natural settling of fly ash, low dust removal efficiency, and serious environmental pollution.

5. The boiler is equipped with a patented fully automatic acoustic soot blower, which effectively reduces the pollution of fly ash on the heating surface of the boiler, thereby maximizing the boiler's service life, ensuring boiler efficiency, and solving the disadvantages of traditional boilers that rely on vibration cleaning or steam soot blowing, which can easily cause damage and wear to pressure parts.

6. The lower part of the boiler ash hopper adopts a two-stage air lock to achieve flue gas side sealing and fully automatic ash cleaning, which solves the disadvantages of traditional boilers relying on manual ash cleaning, such as low efficiency and high labor intensity.
