electric boiler agent with fan core system

How to maintain the electric heating boiler after shutdown? Electric heating boiler furnace internal corrosion maintenance shutdown method, Yaoan shutdown the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry. When long-term disabled electric heating boiler, furnace should pay great attention to external corrosion and maintenance problems. First, electric heating boiler shutdown cooling, heating surface must be thoroughly cleaned of fouling and ash grate the upper, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Such as electric heating boiler rooms in low-lying position, the ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If electric heating boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace.

When coal to electric boiler agent with fan core systems, must pay attention to three issues: the "coal to electricity" on the boiler market has become very frequent in engineering, many users in the initial contact with the boiler "coal to electricity" project, will feel confused. In fact, in order to successfully carry out coal to electric boilers, we need a good grasp of a series of precautions coal to electric boiler; so that on the one hand help to improve the operational efficiency of the boiler after the successful transformation, the other is able to boiler operators increase the protection of personal safety, followed by fast boiler came to tell you about the three key considerations during power coal boiler.

At present, the progress of technology and the capacity of circulating fluidized bed boiler in China increase, domestic CFB boiler will gradually play a positive role in China's electric power production and environmental protection, ZG circulating fluidized bed boiler combustion technology in low NOx is mainly reflected in the reduction of NOx combustion emissions, specific measures in:

1.One or two wind layout optimization method: one or two wind layout optimization can improve the grade of air, which can not only strengthen the oxidation zone and reduction zone hypoxia burnout piecewise low NOx combustion effect, but also inhibit the temperature and the temperature at low nitrogen level, and high efficiency combustion of a high degree of unity.

2.Flue gas recirculation technology: the use of flue gas recirculation technology, an oxygen content of air is reduced to 17% to 19%, while maintaining the flow of state, strengthen the staged combustion furnace, and further promote the circulation of the fly ash amount inside and outside of the furnace, so that the bed temperature decreased, have beneficial effects on the low nitrogen and high desulfurization process.

3.Measurement and control system: by measuring the precise flow can achieve the following main purpose and effect of the secondary air flow can be measured: one or two; one or two wind can be adjusted accurately, the staged combustion can be precisely controlled; combined with the flue gas CEMS, can realize the closed loop adjustment; can keep unit in low nitrogen condition; coordination control the combustion efficiency of nitrogen oxide and boiler.

The party soon provide us with three hot water boiler output foot, gas combustion, efficiency is very high, for us to save a lot of fuel costs. Moreover, these hot water boiler can be achieved by adjusting the full 24 hours a use hot water to meet the daily needs of old people. --customer feedback
