Huadian Global-International Shiliquan Power Plant's “Research and Application of 400t/h Pulverized Coal Furnace Direct-fired Blended Straw Power Generation Technology†project was passed on March 21, 2007 in Zaozhuang City, Shandong Province. Identification of the organization's technical achievements.
Experts from 10 units including Tsinghua University School of Energy and Power Engineering, China Power Technology Market Association, Shandong University, China Huaneng Group, etc. form an appraisal committee. The appraisal committee believes that:
1. Developed a DC straw burner according to the characteristics of four-corner combustion, which solved the matching problem between straw burning and pulverized coal combustion. When the amount of straw is 20% (heat), the furnace is stable and easy to adjust, and the thermal performance of the boiler is not significantly changed. The combustion technology is the first in China, and can provide technical reference for the transformation of the four-corner burning pulverized coal furnace mixed with straw.
2. According to the site conditions, the straw powder pneumatic conveying system with a length of 370 meters was successfully developed and designed to solve the problem of long-distance pneumatic conveying of straw materials.
3. Successfully designed and built a collection, storage, transportation, conveying, crushing and burning system that consumes 100,000 tons of straw per year. Through testing and operation, a number of valuable process design and operational data were obtained. The overall transformation of the project is small and the investment is relatively low. The implementation of the project has reduced the consumption of fossil fuels and has good environmental and social benefits.
For the first time in China, the project has realized the burning of straw on pulverized coal boilers, which is at the leading level in China. The appraisal committee unanimously agreed to pass the technical achievement appraisal.
