Methods for judging abnormal operating conditions

To judge the abnormal operating conditions of the grate furnace, we first need to rely on various monitoring methods. Modern grate furnaces are usually equipped with a variety of sensors such as temperature, pressure, and flow. These sensors can monitor the operating status of the furnace in real time and provide important data support. By analyzing these data, operators can quickly identify abnormal conditions of the equipment.

In addition to relying on sensor data, the operator's experience and judgment are also an important part of judging abnormal conditions. In some cases, even if the sensor shows normal, the operator may judge the abnormal state of the grate furnace by observing the color and smell of the flue gas. For example, black smoke usually indicates incomplete combustion, and if there is a pungent smell, it may be that the fuel contains too many volatile substances, which require timely handling by the operator.

1. Abnormal grate temperature: The operator can improve the combustion conditions by adjusting the air supply. Generally speaking, the combustion process of the grate furnace needs to maintain an appropriate air ratio. Too much or too little air will affect the combustion efficiency. Therefore, the operator needs to adjust the opening of the air valve in time according to the actual situation to ensure that the combustion environment in the furnace is in the best state.

2. Uneven fuel supply: The operator should check the fuel delivery system in time to ensure that the fuel can be evenly distributed on the grate. If it is found that the fuel supply on one side is insufficient, the normal operation state can be restored by adjusting the speed of the conveyor belt or manually adding fuel.

3. Grate blockage: Cleaning is the most direct and effective solution. In actual operation, regular maintenance and cleaning are essential. By regularly checking the grate and fuel delivery system, blockage can be effectively prevented. If blockage occurs, the operator should immediately stop the furnace for cleaning to avoid greater losses.
