Hot sale 3 pass water tube industrial steam boiler

The main heat exchanger is mainly produced by the Italian company Jia XX, other brands have similar technologies and processes, there is a certain amount of use in Europe. Made of 306 stainless steel, the domestic manufacturers had a laboratory test had the relevant parameters biased in favor of 304 stainless steel. Since the factory said to be 306, we tentatively called 306 stainless steel. The card Va, B license, A licensing other manufacturers are often employed in the form of the main heat exchanger. Analysis: Starting from such a main heat exchanger requires the production process. The plant on the 306 stainless steel pipe wall thickness 0.8mm disc commercially available machine, in a cylindrical disc type, pressure at both ends, the tube was compressed into oval tubes. Because of the longer tube can not be completely uniform scratch in the end, so that during the pressing process, there will inevitably be the case of a partial cut through the flat pipe, and insufficient local flat tube, resulting in uneven diameter, so the use of the segment (cell) method pressed. Such rejection rate is reduced, the yield can be improved, but also can be designed to a fixed power (8-10KW / section) of each cell. So you can always add and subtract the number of boiler according to design, adjust the power numbers. But this creates new problems, not butt weld between two units, one welding operation is no space, one is butt-welded seam is annular throughout the main heat exchanger, annular weld to half of the slit 900 in the barrel of a high temperature, to be in the half of the outer tub 200, and the same coefficient of expansion, we can not find a suitable welding consumables. Since not welded in series, so manufacturers using parallel method, several units in parallel in a sub-manifold, so that a four-way water warmed in the main heat exchanger, the problem is solved. As a result of the way just division multiple tube form, the diameter of each cell must be greatly reduced, thinner diameter, is about 30% of the normal section of the tube. In the water quality and good after-sales service in Europe, the use of relatively normal.

How to choose low nitrogen low - NOx boiler as a lower-emission boilers, already into the global market and is the favorite of many customers. But most customers do not understand the extent of their depth, or lack of professional advice that the ideal purchase for less than the hearts of low nitrogen boiler. So how to choose high-quality low nitrogen boiler? Our customers can adopt the following methods: a low nitrogen oxide emissions of nitrogen boiler burners is generally used in premix burners, the burner operation due process in the use of ultra-low nitrogen premix combustion technology can be It contains a proportion of gas and combustion air to an optimal state, and therefore to achieve complete combustion of the gas, reducing the nitrogen oxide emissions. Thus the customer when choosing a low nitrogen boiler, which can pay more attention to the structure of the burner, or combustion gas was observed, to verify the degree of nitrogen oxide emissions standards. Second, the thermal efficiency of the boiler capacity of low-nitrogen high-boiler than in conventional boilers, composed of high-quality stainless steel, heat resistance and better corrosion resistance, and therefore the thermal efficiency is also improved. Customers can carefully observe the material in the selection process, to confirm whether its performance requirements. In addition, also pay attention to its capacity, to see what kind of design, the boiler water flow, water level fluctuations status. Quality low nitrogen boiler, thermal efficiency and capacity of the technology must be advanced. Third, the operational noise intensity Ruoyi to choose low-emission, high thermal efficiency of the boiler low nitrogen, customers can go to their attention operability and noise intensity. Quality low nitrogen boiler with intelligent control of the liquid crystal panel, the platform can interface with intelligent control, fully automatic operation. The customer shall focus on how the control system of the boiler, convenient degree operation. At the same time, the process needs to pay attention to the noise generated by the boiler operation, low noise intensity boiler should only be included in the selection. That is, the above-mentioned three ways to select high-quality low nitrogen boiler, in addition, it can also be analyzed by a variety of factors of production scale, market reputation and so on. Meanwhile, little attention boiler sales or low nitrogen Ranking Trade Ranking may well be a convenient solution. Only low nitrogen boiler energy saving, advancing with the times, in order to seize market opportunities to win customer favor.
