elctric hot water boiler

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!
