Hot water tube boiler a 192 in holland convection tube bundle fouling treatment: hot water boiler in the long run, there will inevitably be fouling phenomenon. Just as there will be people thinking jam after a long labor, slow reaction. But the hot water boiler fouling is different from the human brain appear to be in time, or else will result in burst pipes. After the general approach is the use of a chemical treatment, acid washing or alkali washing, the method may be dipping or cleaning cycle, it may be bonded to both! Intractable scale but some special methods have taken up! Hot water boiler scale appeared we should remain rational mind. First you have to analyze the scale of the category. Analysis of the first category scale, the first mechanical descaling, and chemical methods using the above-described descaling. Before the boiler needs to be designed for the analysis of water content, and water pre-treatment, until the water quality standards to enter the convection bank, or need to be re-treated.

No electric steam tube boiler a 192 in holland combustion chamber, does not need a chimney, regardless of the issue of heat loss, thermal efficiency can be maintained at about 98%, and using a variety of advanced control systems, such as automatic sewage, scale alarm. All the advantages and use it to get the trust of more and more users.

Fault troubleshooting and high pressure steam tube boiler a 192 in holland high pressure steam boiler by a high pressure apparatus commonly occurring, to achieve output energy than the normal pressure steam or hot water higher temperature transducer mounted device. Good quality high-pressure steam boiler temperature due to structural, long-lasting operation, reasonable water system advantages are widely used in various industries. But users in the use of high-pressure steam boiler will be some failures, grasp the essential method to exclude these faults. 1, high-pressure steam boiler overpressure failure phenomenon occurs. Failure performance; and a sharp rise in air pressure than the rated working pressure of the license, pressure gauge pointer significantly exceeds the red line area of ​​security, even after the safety valve still can not stop the rise in air pressure abnormality. Solution: immediately weakened rapidly warming temperatures, emergency shutdown, and manually open the release valve, while increasing water supply, sewage strengthen the lower drum to ensure normal water level in the boiler in order to reduce the temperature of the pot, thus reducing boiler drum pressure. Note: Do not solve the problem immediately turned to run, it should be full of high-pressure steam boiler inspection equipment parts line. 2, high-pressure steam boiler appeared full of water phenomenon. Failure performance: high-pressure steam boiler water level abnormal means that its water level even higher than the normal water level is invisible table, glass in the water table color warning colors. Solution: First, to determine the size of the full amount of water, mild or severe full of water filled with water; then close the water table, even on the water pipe open drainage action several times to see whether changes in water level can resume normal water level is slight filled with water, if found serious immediate shutdown should be filled with water and turn on the water, to conduct a comprehensive inspection. 3, high-pressure steam boiler water shortage phenomenon. Fault performance: a high pressure steam boiler water level is significantly low, and below the normal water line, while the boiler flue gas temperature is increased, the water flow can be significantly less than the flow rate of steam smell burning smell. Solution: emergency shutdown, but non-blind, add water to the boiler, to determine a good or a serious water shortage after severe water shortages in the slow addition of water to the boiler, and at the same time reducing fuel and strength of the wind blast. 4, the steam inside the high pressure steam boiler tube boiler occurs. Failure performance: to be greater than the amount of water in the boiler steam flow, although the increased water flow but still unable to maintain normal water level. Solution: In this case should be maintained to run at reduced load short time, until the boiler slow to a stop, and finally the withdrawal of the remaining water in the furnace, the furnace temperature and reducing the pressure, which is determined blast furnace and isolated from other steam main pipe. High pressure steam boiler in the course often due to improper external operation, maintenance or equipment unreasonable own merit, and many other different faults that may occur, the operator has some prior knowledge of and failure factors may arise, may try to avoid these improper handling pre precautions during use, it can also quickly determine if a failure occurred and remedial action.

In mid-June this year, Hebei Province issued a notice regarding the development of gas-fired tube boiler a 192 in holland nitrogen oxides (referred to as NOx) governance, in order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, will gradually nitrogen oxides exceeded boiler discharged for investigation and control work, high nitrogen oxide emissions from the original (150mg / Nm3 or above) is reduced to 30mg / Nm3. City, Hebei Province is located in the Yili Dairy Co., Ltd. to respond positively to governance EPA gas boiler NOx reduction, and led the way, three of the company's existing 15 steam tons / hour (t / h) gas steam boilers for low-nitrogen emissions transformation.
