cheap price good quality instant heating solar 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 cheap price good quality instant heating solar 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.

What are the main parts of the cheap price good quality instant heating solar boiler? No matter what kind of equipment, accessories are essential, and parts of the boiler is very much, even the smallest one ton tonnage industrial gas boiler, but also by the composition system accessories, not to mention the large circulating fluidized bed the number of parts of the boiler. Zheng pot boiler accessories is one of the main marketing services provided, as even wear tiny boiler, but also need to replace individual parts within a certain period of time, to ensure safe and stable operation of the boiler.

Key condensing gas cheap price good quality instant heating solar boiler condensing boiler key point is that condensing technology, is a new energy-saving, environmentally friendly technology; in fact, the principle is not complicated, simple generalization is the flue gas heat recovery through flue gas condensation. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, or even higher, so that water produced during combustion of the fuel (e.g. natural gas: CH4 + 2O2 → CO2 + 2H2O) is in a state of steam superheater in the flue gas, with the smoke. the loss of gas from the chimney. Traditional boiler thermal efficiency is generally only 85% to 91%. The Henan fast condensing gas boiler side, that the exhaust gas temperature is reduced to 35-60 deg.] C, sufficiently recovered latent heat of condensation and sensible heat in the flue gas water vapor, maximum thermal efficiency of up to 108.9%.

20th Meeting of the Standing Committee of People's Congress of the fourth Jinzhong City, approved the Thirteenth People's Congress Standing Committee of Shanxi Province, the seventh meeting since January 1, 2019 the formal implementation of the "Jinzhong City coal pollution prevention and control regulations "(the" Ordinance ").
