using boiler for hot water

How to solve the fouling problem of Gas-fired BoilerIt is well known that gas-fired using boiler for hot waters are energy-saving and emission-reducing products, so they are loved by many customers, but in use because of the water quality problems, the boiler will form scale, then how is the scale formed? What should we do about it? Formation of boiler scale: after a long period of operation, the boiler inevitably has the problem of scale and corrosion. The main reason for the formation of boiler scale is that there are hardness components in the feed water, and after high temperature and high pressure, the boiler is continuously evaporated and concentrated after high temperature and high pressure. A series of physical and chemical reactions take place in the furnace, eventually forming a hard, dense scale on the heated surface. So the harm to the boiler can't be ignored. The heat transfer effect is reduced and the corrosion is caused by the corrosion under scale, which results in the decrease of heat absorption in the boiler water wall furnace, the increase of boiler outlet temperature, and the increase of boiler loss. After scaling in the water wall, the heat transfer effect is reduced, which may lead to the increase of the temperature in the wall of the water wall and the explosion of the tube in the water wall, which affects the safe operation of the boiler. Scale is boiler; The first is the main cause of boiler accidents, and its harm is mainly manifested in the waste of a large amount of fuel: because the thermal conductivity of the scale is only a fraction of that of steel, the heat transfer will be blocked after scaling on the heated surface. In order to maintain a certain output of the boiler, it is necessary to raise the temperature on the side of the fire, so that the direction External radiation and smoke exhaust cause heat loss. Now we can use efficient, environmentally friendly and non-corrosive cleaning agent to clean gas-fired boiler. The cleaning agent completely dissolves the cleaning scale, so that the tube of the equipment can be exposed to the original metal color, and the influence of scaling and biological algae sludge can be reduced. At the same time, it can peel off iron oxide and ferrous oxide, prolong the service life of gas-fired boiler and reduce energy consumption.

Concern the 2014 APEC summit (referred to as APEC), held in Beijing Huairou Yanqi ecological demonstration zones on November 10, multinational leaders are to attend an important meeting. The summit venue construction attaches great importance to environmental protection work. In selecting venues using boiler for hot water heating and hot water services, to the summit to make clear that emissions of nitrogen oxides boiler, perform extremely strict NOx emission standards around the venue --60 mg / cubic meter. Carefully selected, nitrogen oxide emissions technology in the international advanced level of fast Boiler become the ultimate winner. Gas hot water boiler fast boiler developed the production of ultra-low nitrogen oxide emissions, gas steam boiler, integrated condensing boiler has become the summit heating and hot water designated products.

Low temperature hot water using boiler for hot water has a hot water boiler and sub-temperature hot water boilers it. States have the high-temperature water and cold water at different temperatures boundaries of our country as a dividing line at 120 ℃ temperature, that is, high-temperature hot water boiler water temperature higher than 120 ℃, the otherwise low temperature hot water boilers.
