Inside the Fangkuai water parameters for water tube boiler plant, there is a special corrugated furnace bladder production line, which can be processed according to the computer setting mode. At the same time, this is also a unique processing technology of Fangkuai Boiler. The cost of natural gas fuel alone exceeds 5 million yuan per year. The corrugated furnace liner fired by this production line can not only increase the heating surface of the boiler, but also alleviate the damage caused by the thermal expansion and contraction to the combustion chamber, and greatly extend the service life of the boiler.
Boilers are our life's products, and gas-fired water parameters for water tube boilers are energy-saving and emission-reducing products, which are loved by very customers, but in the use of gas-fired boilers, due to the problem of water quality, the boiler will be covered with scale. What is the effect of the scale on the boiler? The formation of boiler scale after a long period of operation, the inevitable occurrence of scale, corrosion problem, the main reason for boiler scale formation is that the water has a hardness component, after the high temperature, high pressure evaporation concentration, the main reason for the boiler scale formation is that the water has a hardness component, after the high temperature, high pressure evaporation concentration, A series of physical and chemical reactions take place in the furnace, eventually forming a hard, dense scale on the heated surface. Harm to gas-fired boiler 1 The heat transfer effect is reduced and the corrosion factor under the scale is 2, which results in the decrease of boiler water wall furnace heat absorption, the increase of boiler outlet temperature, the increase of boiler loss 3, and the reduction of heat transfer effect after scaling in the water wall. It may lead to the increase of the wall temperature of the water wall and the explosion of the tube wall of the water wall, which will affect the safe operation of the boiler. Scale is the first harmful factor of boiler, and the main cause of boiler accident. Its harmfulness is mainly manifested in the waste of a large amount of fuel: because the thermal conductivity of 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, thus Causes external radiation and exhaust smoke to cause heat loss. Boiler cleaning gas-fired boiler can use high-efficiency environmentally friendly non-corrosive cleaning agent to clean gas-fired boiler, cleaning agent to clean the scale completely dissolved, so that the equipment tube exposed metal primary color, reduce the effect of scaling and biological algae sludge. 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.
Lincang compact steam water parameters for water tube boiler apparatus so that the selection of many units are in fact quite small amount of steam boiler plant of supply and demand, whereby the miniaturization of such devices, also known as steam steam boiler, in accordance with the burner temperature reaches 100 deg.] C, will rapidly produce steam, thus achieving the production needs of customers. This is we often want to know the size of the steam boiler plant. Thus you how to choose a steam boiler plant, in fact, we generally can be with their own strengths to choose from fuel steam boiler plant, some customers to power their own, we can choose the steam boiler plant electrical energy can significantly cut their own cost of. If the device size is extremely large steam boiler, gas pipeline will not open, you can choose biofuel steam boiler plant, can weaken fuel costs, in accordance with its own production of biofuels, can rapidly reach the burning fuel. If the value is extremely small steam supply and demand, can choose often said steam engine, to achieve great demand with a small fee!
Note that, these condensing water parameters for water tube boiler cleaning errors occur frequently in many condensing boilers manufacture, transport and installation in a variety of situations will occur, so that the pipe wall boilers accumulate a large amount of dirt or other impurities in the oxide, resulting in the initial boiler run directly heating surface corrosion damage. To this end, boiler manufacturing companies will configure a set of operating instructions for each condensing boilers, including cleaning this one. Then the process consumers condensing boiler cleaning in which errors can strayed, how to avoid it? A chemical cleaning process does not detect the chemical analysis is a very rigorous chemical cleaning process. But if chemical cleaning is not complete, some dirt is not completely clean; and if the cleaning time is too long, there will be over-wash phenomenon; good cleaning effect, a secondary cleaning will waste of raw materials, and waste time. Which will increase the erosion had washed condensing boiler, condensing boilers metal pressure caused by a reduced ability of the normal operation of condensing boilers after impact. Improvements are: chemical analysis must be prepared to detect chemical cleaning processes, test once every tens of minutes acidity, total iron ion concentration, PH value. When two close data laboratory analysis, chemical cleaning end point is reached, and be discharged after reaching the neutral acid. Second, chemical cleaning is not performed after completion of the passivation process is the process of passivating the clean surface of the condensing boiler deactivators re reaction. Since the control point passivated more stringent requirements, if not properly controlled, the passivation will fail, and if the pickling is completed, and only a simple cleaning is finished, which makes the surface to be cleaned boiler condensate prone to two secondary rust, scale condensing boiler capacity decreases, prone to rust improvements: condensing boiler after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled total iron ions concentration. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation. It can be learned from the above, chemical cleaning condensing boiler there are more abnormal phenomena, and that the life of the condensing boiler, safe operation, energy production had a negative impact, therefore, in order to eliminate these abnormal phenomena, sustainable development and safe use of condensing boilers environment has a very big role.

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers.
