During routine inspections, operators should use their ears to listen, their eyes to see, their noses to smell, and their hands to touch. The identified abnormalities are then analyzed comprehensively, and the equipment’s appearance, temperature, pressure, odor, sound, etc. are compared with those under normal operation, in order to make accurate judgments and eliminate potential hazards. Routine inspections generally include the following: checking whether all manholes and inspection openings on the boiler itself are airtight, whether the insulation is intact, whether the expansion indicators show correct readings, observing the color of the flame and whether the boiling is normal, as well as checking for any abnormal noises or leaks in the various heating surfaces. Check whether there are any leakage or vibration issues in the various steam pipes. Verify that the safety valves, exhaust valves, feedwater valves, and cooling water valves are in the correct position with no leaks, and that the connecting rods are not bent or stuck. The positions of the primary and secondary air dampers are correct, and the connecting rods are not detached. The coal feeder rotates properly, without any jamming or vibration; coal discharge from the hopper is normal, the bearing temperatures of the fans are within normal ranges, there is no abnormal vibration, and no unusual noises are heard. The lubricating grease and oil levels are normal, and the cooling water flow is unobstructed. There is no shaft misalignment; the shaft seals are tight, the couplings are firmly connected, the safety guards are in place, and there are no sounds of friction or impact from the moving and stationary parts. The bottom angle bolts are not loose or detached, the slag discharge machine is operating properly, and there is no jamming or detachment of the large and small chains.
