How to ensure the normal operation of the layer combustion boiler deaerator device (1) when the unit normal operation, close the top deaerator exhaust pipe line two electric stop valve, exhaust steam discharged through the orifice plate. (2) steam turbine load rejection, when the unit enters the oxygen pressure is less than 0.15MPa extraction apparatus should automatically close the door extraction, steam source and alternate emergency opening administered automatically adjusted so that the pressure was maintained at 0.15MPa pressure oxygen apparatus made up pressure run. When the standby off steam source outage to the pump, close the inlet, outlet valve, the device enters the deaerator outage state. (3) boiler oxygen equipment under normal operating conditions such as found defective water oxygen content may be appropriately open a large degree of opening of the exhaust valve. (4) should always supervise the operation level, so that the water level should be maintained at a normal value, when the water level is too high or too low water level regulator should automatic operation, such as the failure promptly. (5) during normal operation, valves, water gauge, pressure gauges, thermometers, etc. should be complete, sensitive and reliable, and should always check. (6) by operating procedures required timing detection and recording equipment operating oxygen pressure, temperature, water, oxygen, and water output parameters.
Z: vertical type. Using the "D" type arrangement, arranged longitudinally down drum, as the flue gas flow partition Wall full mode, the left side of the boiler convective tube bank is arranged.
Chinese hot water layer combustion boiler series of parameters are: rated thermal power 0.1-116MW, allowable working pressure 0.4-2.8MPa, rated water temperature 95-180 ℃. Low pressure hot water boiler for his work without the supervision and control of water level, so its structure is simple, easy operation and maintenance, ease of manufacture. But there are some special problems of work: hot water boiler must ensure that no vaporization occurs, in order to avoid water hammer; internal and external corrosion oxygen acid corrosion of Low Temperature more serious; sudden power outage, the pot water flow generated by vaporizing Wait. These issues must be considered in the structural design of the hot water boiler, manufacture and operation maintenance.
After use throughout the winter, the Central Conservatory of Music give us feedback, six V6-99 fully meet the heating needs of the school. And layer combustion boiler fuel and water requirements are not high, urban water and low-pressure natural gas combustion can operate. The most important point is that nitrogen oxide emissions are very low and very happy to recommend it to others to do the brother of boiler units. --customer feedbackFree Chat
