2023, Dongfang hopes that Qianjiang Cement Waste Heat Power Generation Project will gather wisdom, pool strength, climb over the hill, twist all cadres and staff into a rope, make every effort to build a force field to reverse the status quo, shoulder heavy burdens and overcome difficulties, and reverse the decline of power generation indicators in July at one stroke. It has achieved a qualitative leap in production indicators with fine management. After the start of the unit after the
spring inspection, the company's important indicators of waste heat power generation per ton of clinker power generation failed to achieve the expected target, and the gap with the indicators was obvious. In July, the indicator fell again. This number is like a needle sticking in everyone's throat, which has aroused the vigilance of everyone in the company.
"Opportunities exist in the concept, in the face of negative problems, we should seek positive ideas and ways to solve problems for decision-making, and build a" force field to reverse the status quo ". Inspired by the latest requirements of Dongfang Hope Group, the company's management cadres discussed and decided to move forward the process management, not limited to the process, and determined to take advantage of the opportunity of minor repairs in August to reverse the status quo, start from a small point, and change the concept of efficiency. The company convenes all employees to hold a meeting to discuss the problems existing in the current production process, and mobilizes employees to actively feedback the problems found in the production process and suggestions for improvement. After layer-by-layer analysis, the factors affecting power generation are listed without omission. After decomposing the objectives, the company decomposes the special topics into special projects, and implements the improvement project tracking and feedback one by one. In view of the problem of low flue gas temperature at the kiln head, the grate cooler of the firing equipment at the front end of the waste heat power generation boiler was cross-checked through the process management, and the arc valve, bypass air door, cold air door and manhole door were checked and rectified one by one. Grate joints of the grate cooler shall be cleaned manually to ensure smooth ventilation. At the same time, the company also carries out strict standards and assessment for the operation of the kiln grate cooler, strengthens the thickness of the second material layer of the grate cooler, and enhances the heat exchange of the second clinker of the grate cooler. After the overhaul, the average temperature of the kiln head boiler increased significantly.
In addition, in view of the low vacuum of the condenser and the existence of dirt and mud, the technicians carried out chemical and physical double cleaning on the heat exchange surface of the condenser in time, and formulated standards to ensure that every stop must be cleaned. At the same time, technicians repaired the side filter of circulating water, restored the water flow to 100%, and increased the backwash of shallow filter to two times to ensure the quality of circulating water. The dirt of the circulating water tank filler seriously affected the heat exchange and ventilation, and the company organized personnel to clean it manually. When the condenser was started after maintenance, the vacuum value of the condenser was greatly improved. Due to the physical wear and tear of the service life, the leakage and ash deposition of the superheater of the kiln head boiler are also another pain point in this transformation. In this overhaul, the boiler was repaired by hydraulic test in time, and the wearing points of the internal elbow were checked comprehensively. At the same time, the heat exchange efficiency of the boiler was ensured by manual ash removal. In the process of transformation, every cadre and staff clearly realized the seriousness and urgency of the current production problems, and they were United and devoted great energy to solving the current development bottleneck.
After a series of detailed quantitative changes, the waste heat power generation project of Qianni finally ushered in a qualitative change. In August, the waste heat power generation per ton of clinker increased by 16%, and achieved the highest value of the year in September, and remained stable in the remaining months. This also fully shows that the development of enterprises is like sailing against the current, not to advance is to fall behind, to break the team boundaries and inherent thinking, to put the work into practice, to find pain points, solve problems, resolve contradictions, seek promotion, make good use of the four concepts, make good use of the standard cycle, and build a force field to reverse the status quo, in order to continuously inject vitality into the sustainable development of the company.
Standard cycle improvement is always on the way, small data improvement is always on the way, and reversing the status quo is always on the way.
