Kaiyue Coal Chemical Gasification Workshop: Achieving Cost Reduction and Efficiency Improvement through Technical Innovations. Author/Source: Kaiyue Coal Chemical. Date: May 11, 2022. Clicks: 12. The gasification workshop at Kaiyue Coal Chemical remains focused on the company’s goals of cost reduction and efficiency improvement, making every effort to carry out various tasks. Regarding the technical upgrades to the coal feeding systems, the workshop’s staff pooled their ideas and used process innovations and technical improvements to find ways to reduce costs, working together to ensure uninterrupted production. It is reported that the coal scale baffle is an important device in the coal slurry preparation section of the feeding system; it is used to control the lifting of the \"slat doors\" on the coal scale, adjust the thickness of the coal layer on the belt of the coal scale, and thereby regulate the amount of coal fed into the scale as well as the water-to-coal ratio in the coal grinder. Due to the unreasonable design and poor quality of the original coal weighing baffle, as well as the small size of the adjustment lifting handle and the material’s unsuitability for welding, the same old problems kept arising during operation, posing a serious threat to the stable functioning of the device. To completely resolve this persistent problem, the staff and workers in the gasification workshop racked their brains, took into account the actual production conditions, and conducted numerous experiments. By using recycled materials, they designed and manufactured new lifting devices, which enabled the production of high-quality water-coal slurry with a high concentration and a proper particle size distribution. This approach effectively improved the ability of the equipment to operate continuously and stably. At present, this device has been successfully tested in Section 702, and it holds great potential for widespread adoption and application.
