Author's note: boiler is not only an important guarantee for production and operation, but also a prominent risk of safe production, constituting the main contradiction factor of "physical defense", and it is necessary to carry out equipment quality standards and excellence activities on a regular basis, and strive to achieve "zero defects and zero failures" in equipment.
The quality and safety management of boiler auxiliaries and accessories is very important. We need to seriously implement the following requirements.
First, the economizer is firmly installed, and there are no trachomalies and cracks in the body. The economizer safety valve, valve and bypass waterway valve are installed in accordance with the requirements and there is no leakage.
Second, the blower runs smoothly without abnormal sound, the shell is intact, the adjustment baffle switch is flexible, there are open and close direction signs, and there should be a locking mechanism. The blower coupling protective cover is complete and good.
Third, the induced draft fan is selected and coordinated, the operation is stable and there is no abnormal sound, the shell is intact, the adjustment baffle switch is flexible, there are open and close direction signs, and there should be a locking mechanism. The oil level of the bearing box of the induced draft fan is normal, and the coupling protective cover is complete and good.
Fourth, there is no leakage of feed water pump, water replenishment pump, and circulating pump (standby water pump, steam pump or water injector). The water supply pipeline must be equipped with a shut-off valve and a check valve to the boiler water supply to ensure that it works well and there is no leakage. The shut-off valve must be installed between the pot barrel and the check valve.
Fifth, the installation of the emergency relief valve of the hot water boiler should be easy to operate, and the discharge port should be discharged to a safe place.
Sixth, there should be insulation measures for the pipes within the scope of the organic heat carrier furnace, and the flange connection should not be covered with measures. Organic heat carrier furnace expander brackets, chimneys, and heat conduction furnace tube brackets should be free of corrosion, deformation, and cracks that affect safety.
Seventh, the daily fuel tank volume of oil-fired boilers is not more than 1 cubic meter, and should be stored separately. The fuel tank should be equipped with an exhaust pipe and lead to the outside, and a fire arresting cap should be installed on the exhaust pipe. The fuel tank should be equipped with a sewage pipe.
Eighth, the wire rope of the non-centralized coal feeding device has no wire drawing and broken strands; The upper coal hopper should have an anti-decoupling device.
