heat recovery systems for boilers
How hot water heat recovery systems for boilers welding is available to ensure quality? Boiler welding process on the one hand is the consideration of welding personnel and technology, is more important is to be responsible for the security of post-boiler, hot water boiler in the process of which, welding is a very important step, more standardized implementation of specific steps : a welding process to achieve aesthetic finish and to ensure the safety effect of welding, and therefore for process evaluation, merit selection. Second, strict test panels, its mechanical properties, from the process to the test board standards, they can really perform welding. 2. Multi welding current automatic welding, such as vertical girth using submerged arc welding, smoke pipe tube sheet using automatic welding. 3. The smoke tube expansion using the first welding (welding to eliminate the gap), welding, then expanding (eliminate the welding) process. For (X-ray, ultrasound) inspection, to ensure that no defects in the welding seam 4..
Phase out coal-fired heat recovery systems for boilerss imperative
2, meet environmental requirements, improve the environment.
If the gas fired boiler to boiler, boiler output in case of the same, C02 emissions can be reduced by more than 26%; S02 substantially zero; the NOx emissions by at least 33%; ash and soot are reduced to zero; Green environmental protection effect is remarkable.
3, reasonable program of boiler rehabilitation programs must be simple and easy to do: less investment and quick, short construction period. Accordingly, the content of the boiler according to the transformation in the transformation of the less the better, and can be taken to change only the furnace combustion apparatus, part of the basic structure of the transformation range as not to exceed the boiler body.
4, the reliability of the gas supply when the gas supply is not reliable, the fuel system may be provided. If you need to re-consider leaving room for coal-fired boilers, should select the appropriate way to meet the requirements of gas.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water heat recovery systems for boilers to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
