　　Introduction to the treatment measures for beam grates

　　Beam GrateWhen there are slight cracks, generally use asbestos rope to fill them, and apply a layer of refractory cement and asbestos powder mortar. If the damage area of the furnace wall is large, causing the boiler support or the surface temperature of the furnace wall to rise abnormally, and the boiler steel frame and hollow beam to glow red, there is a risk of collapse of the furnace wall. In this case, the furnace must be shut down immediately, and manpower must be organized for emergency repairs.

　　If there are only a few refractory bricks falling off from the beam grate furnace wall and arch, or if the outer wall is slightly protruding, monitoring and inspection during operation should be strengthened, and short-term operation should be maintained. Start the standby furnace or plan for a shutdown for maintenance. If the damage area of the furnace arch is large and has lost its function during combustion, the furnace should be shut down, repaired, or rebuilt immediately.

　　If the damage area of the furnace wall or support is not large and the degree of damage is not serious, the excess air coefficient in the furnace can be appropriately reduced to lower the combustion temperature and maintain short-term operation.

　　Beam GrateThe operation is complex, and the boiler operator must undergo professional training. Its operational management model is similar to that of a thermal power plant. The furnace is placed outside the cylinder, and the "furnace" is not limited by the "boiler"; its volume can be large or small, meeting the requirements for combustion and increasing evaporation.

　　Basic elements for improving the quality of beam grates

　　BoilerBeam GrateAccessories are very common cast iron products in the casting process, and it is important to pay attention to their quality. Therefore, the quality of boiler accessories is crucial. First, it is necessary to formulate process regulations and technical conditions for control and inspection from raw and auxiliary materials to each specific product. Strict control and inspection should be carried out for each process according to the process regulations and technical conditions. Finally, quality inspection of the finished castings of boiler accessories should be conducted.

　　Reasonable testing methods and suitable testing personnel should be equipped. Classification and application of beam-type grate vibration: The surface of the grate has a slight angle with the horizontal plane, and the grate section produces periodic vibrations under the action of the motor and eccentric wheel. During vibration, the fuel layer continuously moves towards the rear of the furnace chamber, causing the ash from the combustion to fall into the ash pit at the end of the grate. The characteristic of this grate is its simple structure.

　　The magnetic drive device sealed by a metal isolation sleeve continuously releases heat during normal operation due to the generation of eddy currents. The working environment temperature of the magnetic material continuously rises. When the temperature rises to the rated temperature value, the magnetic performance of the magnet decreases with the continuous increase in temperature, thereby reducing the transmitted force or torque, affecting the normal operation of the magnetic device. To some extent, the operating efficiency of the beam-type grate unit depends on the combustion situation of the boiler. Beam Grate

　　When it comes to combustion, it is necessary to discuss the combustion speed and process of fuel in the furnace, but the combustion speed depends on the time required for the chemical reaction and the time required for the mixing of oxygen and fuel during the combustion process.
