Top pressure suction and temperature in large coke ovens

In the coking industry, the regenerator (also known as a hot air stove or heat recovery stove) is an essential component of the coke oven, used to heat the air fed into the coke oven. The reasons why there are no temperature and pressure measurement holes at the top of large coke ovens with a height of over 6.25 meters may include: 1. Simplification of design and operation: The design of coke oven regenerators is aimed at achieving efficient heat exchange and long-term stable operation. Installing temperature and pressure measurement holes at the top of the regenerator may increase the complexity of design and operation, and may affect the structural integrity of the regenerator. 2. No frequent monitoring is required: The operating temperature and pressure of the regenerator are generally determined during the design phase, and these parameters do not change much under normal operating conditions; therefore, it may be considered unnecessary to conduct frequent temperature and pressure monitoring at the top of the regenerator. 3. Measurement difficulty and safety: The temperature in the regenerator is extremely high, usually exceeding 1000°C, which makes it very difficult to install and maintain sensors in this area. At the same time, exposing measurement equipment to high-temperature environments also poses safety risks. 4. Alternative monitoring methods: Modern coke ovens may employ other techniques or methods to monitor and regulate the operation of the regenerator, such as through computer simulation, remote monitoring, or by installing measurement points in safer and more accessible locations. 5. Maintenance costs: Installing temperature and pressure measurement holes at the top of the regenerator may increase maintenance and repair costs, especially considering the harsh working conditions and the impact of high temperatures on the equipment’s lifespan. The above does not cover all possible reasons; the specific design choices may depend on various factors, including the specific type of coke oven, the technologies used, economic considerations, operational experience, and the preferences of engineers. For a detailed understanding of the design rationale behind a specific coke oven, it is best to consult relevant coking engineers or coke oven manufacturers. .
