Hot water boiler which is not equipped with no impact can cause demineralizer 1, the waste fuel boiler fouling occurs, resulting in poor heat transfer performance of heating surface, so that heat generated by the combustion of the fuel can not be timely delivered to the boiler water, but a large amount of heat is smoke away, resulting in exhaust gas temperature is too high, if the exhaust gas loss increases the thermal efficiency of the boiler will be reduced. In order to maintain the nominal parameters of the boiler, fuel must be increased, thereby wasting fuel. About 1 millimeter scale waste fuel ten percent. 2, the heat receiving surface is damaged due to deterioration of the heat transfer performance, fuel combustion heat is not quickly transmitted to the boiler water, resulting in the furnace and the flue gas temperature. Thus, the temperature difference on both sides of the heating surface increases, the metal wall temperature, a decrease in strength. Under pressure pot, bags and even blasting will occur. 3. Reduce heat boiler output due to the deterioration of the performance of boilers, need to consume more fuel to reach the nominal rate of evaporation. However, with the increase in the scale thickness, the volume of the furnace becomes large, the fuel consumption is limited. Therefore, it is possible to reduce the output of the boiler. 4, the corrosion damage to the metal: oxygen in the water, acid, base materials will corrode the metal surface of the boiler, it is thinned, recess or perforation, thus reducing the power of the boiler, seriously affect the safe operation of the boiler. 5, in addition to improper operation Priming outside, when the boiler water contains more sodium chloride, sodium phosphate, and silicides oil, boiling or evaporation process boiler water, boiler water occurs when soap and organic base when Teng because soda will produce compost. Foam liquid surface, formed soda pool. No softening, easily scalable. Due to the continuous evaporation steam, boiler of calcium, magnesium, high impurity concentration is 30-50 times that of natural water, fouling rate beyond our imagination, only six months to a year, from 1-2 mm.
Put into use new multimedia exhibition is to create a precedent for technological gas boiler display, 360 ° holographic projection, fly screen interaction, interactive sliding screen, multi-radar means touch, smart models, the integration of virtual and reality, really appreciate rapid technology advancement in the field of party.
How to select condensing best sell hot water boiler condensing hot water boiler how to choose? Recently, with the improvement of people's awareness and promotion of low-carbon living national energy saving publicity, condensing hot water boiler increasingly popular in our country. In the face of the market claiming they are a larger number of condensed water boiler manufacturer and the price gap situation, difficult for consumers to determine how to choose a condensing hot water boiler, told us the following selection techniques condensing hot water boiler. Let us first find out what kind of boiler is condensing boiler, and their performance advantages are: this boiler on the basis of the original boiler can be increased by 3-6% efficient, but its comprehensive energy-saving effect is not obvious, mainly because of the way combustion size fire switch. Quasi reason condensing boiler combustion temperature nitrogen oxide emissions are greater than 120mg / m3. But the biggest advantage of this boiler is cheap. Fully premixed condensing boiler, or many professionals say, it is the real concentration. Since the boiler was designed with a deep full-condensation techniques, thermal efficiency as high as 109.1. In addition, all-frequency premixed combustion technology, the boiler 40% energy saving than conventional gas boiler, energy-saving effect is very obvious. As the cost of the boiler, boiler prices much higher than the prices to be condensing boilers, recovery of investment costs over one year takes about a year. The national coal industry in recent years due in large part to change the gas over the past two years, large and small gas boiler manufacturers, has been in short supply situation. At the same time, there have been some speculators, they want to take this opportunity to get back some money. Condensing gas hot water boiler is an energy-saving, environmental protection, safety, technical and service demanding products. Each manufacturer may feel that the Internet is good, but if you go to the manufacturers site visits, you will find a big gap, so it is necessary to go to the manufacturers site visits!
