The daily operation of the boiler adjustment (oxygen papers): oxygen is an indicator to monitor the boiler furnace excess air ratio, it changes the furnace combustion conditions are closely related, if the external loads, combustion, cited air supply, air leakage parameters such as the case where the constant amount of oxygen to the furnace to correspond to fuel heat release. Generally, under stable conditions, furnace heat release amount matches with the supply amount of oxygen remains substantially unchanged, the main steam pressure is stabilized at a certain value accordingly. Oxygen is increased, the furnace described exotherm less than blowing amount, then the pressure will drop, it is required to increase the fuel supply amount, to maintain the pressure. Because of the inertia of the drum and the heat storage capacity of the combustion equipment, the main steam pressure change rate is slower than the rate of change of the amount of oxygen, therefore, concerns the amount of oxygen changes can be determined in advance direction of the pressure change, thereby adjusting the pressure of the functions ahead of the effect of regulation, which is the main basis for regulating a pressure stable operation.

Looking back at 2018, we in the Group 'professional life, work lean, "the core values ​​of the correct leadership, and achieved fruitful results. "Fine positioning, precise process, continued optimization" is the connotation of professionalism we adhere to, in Group tireless efforts of all staff, we have made a number of break points to first academician workstation as the representative of the boiler industry, which in the whole boiler industry are unprecedented achievement, for which we are very proud!

Whether the managed pressure elctric hot water boiler quality and technology supervision department?

Special Equipment Regulations boiler will be the following definition:

Henan gas boiler maintenance (b) a, when one of the following cases, the operator should take urgent measures to cut off the main fuel Henan gas boiler stop running and timely reporting of relevant departments: 1 induced draft fan or blower outage; 2 Henan Gas boiler furnace pressure is too high, can not adjust to the normal range; 3 high drum water level exceeds the specified targets, and still can not turn on the water passes quickly return to normal; 4 drum water level is below the specified target, increasing the water supply into the gas boiler in Henan and take other measures still no water; 5 drum pressure rising pressure gauge has exceeded the maximum value, although the safety valve off, but the pressure is still rising drum; 6 level gauge, pressure gauge or valve failure or damaged, can not guarantee the safe operation of the gas boiler, Henan; 7 water Supply system for water supply and equipment failure has not normally bottled water into the furnace, drum level can not be maintained; 8 pressure element damage, cracking, or severe leakage seal, can not be guaranteed normal production, and even endanger the safety of personnel or other equipment; 9 tubular housing or the like cracks are found, bulge, deformation There is the risk of damage or leaks endanger safety; 10 pipe severe vibration, endanger the safety of operation; takeover, fasteners damaged, it is difficult to ensure safe operation; 11 Henan gas boiler fire or equipment accidents adjacent endanger the safe operation of regular gas boiler ; 12 cases occurred other safety rules are not allowed in Henan gas boiler continues to run. Second, when one of the following cases, the operator should normally stopped Henan Procedure gas boiler, and report relevant: a pressure receiving member weld leak, the safety valve housing severe cracks or failure; furnace tube 2, waterwall tubes, economizer tubes, superheater tubes for various reasons when leakage; insulation material on the inner portion 3 in contact with the flame off the furnace; 4 Henan gas boiler steam superheater tube metal temperature over the allowable bear temperature, when the parties try to adjust or reduce the load and not through the normal slaughter; 5 Henan boiler feed water, steam or water meters gas seriously substandard quality, or affect the production run by the efforts of adjustment can not return to normal.
