Parties were quick to go to Shanxi Changzhi, boiler security popularize knowledge of this year, fast boiler should Changzhi City, Shanxi Province Special Equipment Supervision and Inspection (referred to Changzhi City, the special prosecutor) was invited for Changzhi City, more than 200 enterprises use boilers unit representatives of the gas boiler safety and technical training. Fang fast professional engineers with many years of use awareness of the boiler, in simple terms, the boiler eleven points to secure technical knowledge, has won numerous praise.
Exhaust gas temperature of the heat loss is heat loss of a primary gas boiler, it is mainly dependent on the temperature of exhaust gas with an excess air ratio. In operation, perhaps you want to make sure that decline in the exhaust heat is lost completely incinerated under conditions to improve boiler burning power, boiler exhaust gas temperature too high can lead to thermal power boiler decline.
How to distinguish the correct pressure hot water boilers and pressure hot water boiler, furnace pressure to see changes in pressure hot water boilers and pressure boilers biggest difference lies in the pressure. Even the low-cost pressure hot water boiler, the furnace pressure hot water is always consistent with the atmospheric pressure does not change as the temperature changes; the contrary, because of the pressure boiler furnace and water system is closed containers and piping components will naturally follow with increasing water temperature changes. See changes in pressure in the furnace is a more intuitive way to distinguish between the two. Second, look at the professional level control problems because the supply pressure hot water boiler is not operating pressure, the pressure in order to achieve operation of the boiler circulating pump inlet and the outlet is connected to suction hot water in the heating boiler to a user, users return pipe and boiler water inlet necklace, equal to the amount of water into the water. Thus, pressure hot water boiler water level control problems still top box connected to an opening in the drum full of water, the water level control problems. The pressure hot water boiler water level control is no problem, which is one of two significant differences. Third, look at the structure of constraints pressure hot water boiler on the structural parameters of the issue, compared with pressure hot water boiler much simpler. Unlike the structure of the pressure in the boiler strictly limited boiler capacity, parameters, mounting position, etc., only reasonable pressure hot water boiler heating surface arrangement, water circulation to ensure reliable basis, little limitation on the structure, may be large degree design, construction and installation according to actual needs of users, more flexible and convenient. This is the pressure hot water boiler then more and more important reason for the user's favorite move. In summary, the difference between the atmospheric pressure hot water boiler and hot water boiler mainly in furnace pressure changes, whether the water level under control and whether there are structural limitations in three areas. In fact, the difference between the two is far more than that, they are there is a difference in terms of service life, water supply, safety performance, if you carefully study will certainly find many differences, after contrast, I believe it will not hesitate to choose pressure hot water boiler.
Ordinary water is put into the boiler, which is very easy to scale. Because the steam is continuously evaporated, the concentration of calcium, magnesium and impurities in the boiler is very high, which is 30-50 times that of natural water. The scale of the scale is very amazing, and it may not take half a year to one year. Can have 1-2mm scale. Scale damage greatly threatens the safety of the boiler. In severe cases, it can cause the boiler to burst!
