(1) The burner is not reliably interlocked with the boiler protection device
The incomplete interlock between burner and boiler safety protection device is not the only case encountered by euroguarantee technicians, which has a great potential safety hazard. Individual technical personnel is not strong sense of responsibility, working graph save trouble, only then good home burner and control cabinet connection, only can ensure the boiler ignition and extinction protection device for reliable, but did not pick up the burner to the boiler all the wiring for all safety interlock protection device, which can cause the boiler monitoring temperature, pressure, water level or water safety interlock protection device failure, not reliable.
(2) The user does not strictly implement the responsibility of the safety subject
In the process of low nitrogen combustion boiler transformation, many kinds of boiler unit did not according to the strict supervision organization guidance documents to carry out the enterprise security responsibility, the low nitrogen transformation of check and acceptance of responsibility was to special equipment inspection inspection agencies, but want to combine boiler inspection institutions of the burner to examine regularly inspection cycle, can't be all low nitrogen to build before the boiler running to confirm all the burner. If the user adopts a burner that has not been verified by type test, or a burner with inconsistent main parts and no record, it may bring risks and hidden dangers to the safe operation of the boiler.
(3) Poor maintenance of the burner in use
The maintenance of low nitrogen burners is higher than that of conventional fuel and gas burners, especially the burner with full premix surface combustion. The air filter should be cleaned once or twice a week, and the gas filter should be cleaned regularly. Must guarantee for the whole surface of the premixed combustion burner into the wind flow, if not timely clean strainer, will cause the mesh was dust jam, greatly increase the burner into the wind resistance, when jams has made inlet wind speed is less than the flame propagation speed, can produce tempering, led to the mixture of air and gas cavity indoor deflagration, serious when in furnace explosion.
