Low nitrogen transformation of our mathematical model for wate tube boiler technology is gradually maturing, gas boiler After transformation, not only has a strong impetus to production, energy saving and environmental protection has also done is in place. In Henan low nitrogen transformation boiler tender market can be exposed to a lot of good business transformation, some good boiler supplier for the transformation of the construction program and the follow-up performance is very reliable, so for the user, what type of low nitrogen transformation of business just trusted it?

Advantages and disadvantages of water-tube mathematical model for wate tube boilers SZS gas water tube boilers, gas production base in 20 t / h or more, currently SZS the most popular type of gas pipes, compares it with the fire-tube boiler, no large-diameter drum in structure, rich Alternatively the elastic bending straight pipe smoke tube, not only save metal, and others to improve the capacity of the steam parameters of the boiler to create the conditions. Water tube boiler advantages: 1, the cylinder placed outside the water tube boiler furnace, vary the volume of the furnace, the combustion and to meet the requirements of increased evaporation. 2, water tube boilers generally do not directly heated drum, in order to accommodate the tube was placed in the furnace water vapor, flue heating surface for heat transfer performance and safety can be significantly improved. 3, the water preheating boiler water, soft drinks and the steam superheater in the economizer heating surface, the water wall tubes and convection superheater completed. 4, water vapor boiler system, combustion system and the secondary system is more complex, but the structure of a single water tube boiler pressure parts is relatively simple. 5, since the water preheating boiler water, soft drinks and superheated steam is done in the tube, the tube fouling difficult to remove, and therefore require a higher quality of the water tube boiler, running, operation and management also requires a higher level. Water tube boilers Disadvantages: 1 structure is complicated, manufacturing costs than the fire-tube high, and clean up the trouble. 2. The impact caused a large scale, strict quality requirements. 3. Because the steam drum water reservoir, the water drum capacity is small, it is easy to cause priming phenomenon, the steam generating high humidity. 4. Water prolonged contact with hot combustion gases, easily damaged. The storage capacity of steam is small, so the pressure fluctuation is large.

Recently, China's 21th National Assembly HVAC academic year in "Swan City" - Sanmenxia City, Henan Province began. This annual meeting embodies the HVAC industry leading experts, technical design schools scientists, representatives of major HVAC manufacturers and industry media, nearly 20,000 HVAC colleagues attended the meeting.

More economical steam mathematical model for wate tube boiler can play a role in energy saving produced by the steam boiler is high-pressure gaseous, during use, a large amount of steam can be generated, so the use of the pressure vessel, in which a related aspect there is a certain provisions, whether used or installed must comply with some aspects, and apply the relevant evidence, but also to accept the annual inspection. This boiler used in the printing and medical care more. If the hot water boiler is produced, so it is not pressurized container, are often used in our lives, is relatively small in terms of investment, use of the process, management costs are very low, of course, will be more secure. Some schools or community-related, may also be related to the use of this method of heating water, relatively speaking, it will be more convenient. Steam boiler in the structure, allowing fuel to burn more fully, and in the process run more stable, can really improve efficiency, which would allow users to better reduce costs, the whole of it will be more use more protection. Many places are in use, can play a role in energy saving, and relatively more economical, so that it can use real protection. From the analysis of the specific works, the use of the process, the main heating device to release heat, then by a certain conversion, a large amount of steam, and the steam trap correlate. Use of the process, increasing the temperature of the steam is then able to reach the required temperature. This works, this works can improve work efficiency, and truly play a better role. Structure and principles of steam boilers, this area will affect the future use, advance the understanding of the relevant circumstances are, and have the knowledge of the whole of use, which for us will have more benefits, so be sure to do ahead of time to consider. Before purchasing equipment, we have to confirm in advance that these circumstances device, so that it can ensure that the specific choice of fruit, you can also make use of the process more smoothly. Different devices are not the same in construction and principle, let me use the process, there will be different results. Structure and principles of steam boilers is what, to correctly do know these aspects, then the future in the selection process, will have a corresponding basis for these people to purchase provides choice, so we have to advance to do a good understanding.
