The recent good news story: Union Square soon Group was named the provincial Federation of factory affairs leading group as "micro-small and medium private enterprises in Henan workers' congress building demonstration units" honorary title. Win the title, is inseparable from the efforts of all labor union workers, they work with their own solid foundation, effective operational mechanism and splendid achievements successfully nominated and award winning. Over the years, the Labor Union under the correct guidance of urban levels of trade unions, under the correct leadership of the Party, Comrade rely on the staff, smooth internal management channels, good to play the democratic management of conflicts "relief valve" business "stabilizer" and developing the "catalyst".

What precautions when using industrial boilers? Mainly to provide the industrial production of energy and other power production in order to maintain a power device of its manufacturing operations, one of which is a major steam-powered electricity or gas to maintain the use of industrial boilers, another is based on coal providing power to maintain the operation of the production as raw materials by recycling waste heat boiler traditional industries, it is widely used in industrial production. So, when people use professional industrial boilers need to pay attention to what matters it? First, the operating personnel in the use of industrial boilers operate not only need to have the relevant knowledge and proficiency in operating skills, but also in the operation of the boiler should be run strictly prohibited without leaving their jobs so that the boiler is in a state of neglect, reduce accidents caused by the furnace excessive pressure or pot water level is too high and so on. Second, the staff undergo a rigorous technical evaluation before the relevant professional departments should be adjusted to improve the working pressure in the industrial boilers, pressure gauge and a safety valve to avoid common cause failures industrial boiler overpressure phenomenon appeared to mislead the operator allowed to adjust make mistakes, we should also strengthen the operational skills related to operating personnel so that timely treatment is not a normal phenomenon during boiler operation. Third, before use should be fully checked industrial boilers and boiler configuration check voltage is in the normal current value, the structure of the boiler to avoid unreasonable or poor welding quality and safety accessories related failures caused by the occurrence of industrial boiler runtime accident while before using the boiler should also be adequate treatment in order to be able to reduce accidents during the operation running. These are the three issues of professional industrial boilers in the use of the relevant operators should be noted, strict attention to its use handling precautions can effectively avoid improper operation caused an accident when using a boiler, while improving industrial production to a certain extent efficiency, selected first-class industrial boiler manufacturers can better protect their quality in the selection of industrial boilers used in industrial production.

Steam boiler When should an emergency shutdown when the steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.

How to protect the evaporation boiler reaches design: In order to stabilize the combustion, if the coal volatiles, reducing the amount of heat necessary to increase the excess air ratio, the boiler furnace flue gas temperature to be reduced and the amount of evaporated water wall decreases, the radiation furnace transducer heat formula indicates, the furnace flue gas temperature to reduce the influence of the radiation heat transfer is the fourth power of the relationship.
