plc controll steam boiler

Industrial plc controll steam boilers which protection device which protection of industrial steam boiler have? Boiler safety protection control in accordance with national professional standards for boiler industry, Technical require control, the main security function of the gas is as follows: 1, gas pressure abnormal protection: high pressure, low pressure will generate an alarm signal, and stops the ignition process; 2, wind abnormal pressure protection apparatus: high pressure, low generates an alarm signal, and stops the ignition process; 3, leakage protection device: when gas leakage is found, an alarm signal is generated, the ignition process is stopped, safety shut-off and start release system. 4, flame protection means: when the flame was found, an alarm signal, stop the ignition process. 5, a high pressure steam boiler, an alarm signal, if the pressure continues to rise to the high critical point, then immediately enters an emergency shutdown state; 6, when the boiler water level is low, an alarm signal, if the water level continues to the downstream extreme lows, boiler emergency stop; 7, when the boiler failure or emergency stop signal is issued, will enter the emergency stop state. 8, flue gas overheating: when the flue gas temperature exceeds the set value, sound and light alarm; 9, automatic power protection: when the external power sudden power failure, emergency shutdown state entered immediately, need to restart the operation, the boiler can operation; 10, blower protection: when the stage is open and the fan motor overload, thermal relay, fan power off, emergency shutdown conditions.

It is reported that fast boiler opportunity to help APEC summit, with more than Institute, universities collaborate to jointly develop the latest ultra-low nitrogen oxide emissions control technology, nitrogen oxide emissions will be maintained at 33 mg / m within the scope of the emissions has exceeded European standards in the future, this technology will better serve the Beijing as well as the national gas boiler renovation project. "Our vision is to: continue to meet the energy needs of user convenience and energy saving, the fast boiler build the first brand of Chinese clean boiler future we will continue in different areas of ultra-low nitrogen, ultra-low dust, low noise, etc. continue to explore. in order to achieve greater results. "the technician said in conclusion.

What are the requirements before ordinary gas plc controll steam boiler operation? Ordinary gas steam boiler put into operation before the needs of internal and external view, especially the new device or by severe pressure parts of the boiler repair, it is necessary by the inspection departments. In practice using steam boilers by the preliminary inspection, after renovation standards, it can be started. Details are as follows: 1, ordinary steam boiler equipment and environmental conditions to fit the relevant rules "boiler safety inspection skills Regulations". Boiler steam boiler is necessary to obtain a registration card use and useful during the regular inspection of boilers reports. 2, the need to build a separate boiler room, boiler room in the basement or the roof can not be built, the demand by fire and other tests. 3, to equip professional licensed fireman, fireman people need to fit the relevant rules "boiler fireman who apply the rules of safety review" of the State promulgated water quality testing should also hold certification. 4, steam boiler fuel should be used or planned fuel near the fuel plan. 5, boiler room necessary to complete the detailed rules and regulations. These are the common requirements before steam boiler into operation, according to the steam boiler 30l the following "safety skills boiler inspection procedures" rule-free water capacity is supervisory inspection. Free supervisory inspection of steam boilers Registration does not require installation, no need inspection, do not have to build the boiler room.

Easy maintenance: There are movable smoke box doors in the front and back of the boiler, and there are observation holes and inspection holes in the rear of the boiler, which can be checked and cleaned up in the furnace. The manhole is set up on the furnace body, and the structural design takes the convenience of future repair and maintenance into full consideration.
