The main difference between water-tube heat exchanger and boiler in ethiopias and fire tube boilers What? Water and fire tube inside a tube with medium to define water pipe inside the water to go through the external flue gas convection / radiation heat transfer tube fire tube heating tube inside the flue let go of flue gas heating tube external medium to achieve a simple heat exchange tube boiler water and steam structural changes in a large volume good good adaptability to the structure of a load lower than the quality requirements of water tube boilers are used for small enterprises and domestic production process water tube boiler heating the heating surface is arranged to facilitate heat transfer performance higher for the large capacity and high water quality parameters and operating conditions on the level of requirements (1) to adapt to a wider range of water tube boiler pressure breakthrough pressure of 2.5MPa for reference by limiting meet fire tube boiler steam requirements by the pressure limit for the wall thickness of the material under 2.5MPa pressure (2) fire tube boiler shell type boiler manufacturers of each of the boilers by the current equipment, tooling fabrication limitations too large fire-tube boiler generally difficult 35t / h boiler at boiler water tube structures on large-scale boiler 35t / h commonly used tube structure (3) fire tube boiler with a compact shape and the output characteristics of the same device are lower than the fire tube boiler by weight of water-tube boiler due to bulk More space for arranging large superheater tube boiler thus occupy a relatively large boiler room
It is reported that since December 2018, with the market in Hefei, Anhui Province Lujiang County prison within the jurisdiction of the range 15 "coal to gas" heat exchanger and boiler in ethiopia unit in the course of a full range of checking the newly installed gas boiler, while ensuring the area range within the boiler unit making a smooth transition "from coal to gas," the process, but also to ensure the safe use of the newly installed boiler.
The boiler before proceeding with the installation, install the unit you want to inform the local boiler installation of special equipment safety supervision and management department, inspection units installed during the installation and installation personnel qualification documents related strictly require the installation of the unit perform the required safety specifications and related standards, strict Charles undocumented and undocumented installers to install the unit.
When commissioning the boiler, the gas company and do the docking unit installation and use of the tripartite unit personnel to ensure the safety of boiler commissioning and trial operation of the boiler installation inspection, and actively promote the boiler unit boiler handle registration certificate and make contingency plans .
Factor 2, the condensing heat exchanger and boiler in ethiopia, which has been developed for several years, has been very diversified in type and brand, and there are some differences between different types of boiler in shape structure and internal design mode. Therefore, different design methods will affect the service life of condensing boilers to a certain extent, not only in the later stage of operation, users may also affect the service life of boilers.
How to judge dry gas steam heat exchanger and boiler in ethiopia event occurs when the water level is less than the minimum water level has been identified, but the water level gauge can still be seen, identified as mild water; not observed when the water level meter, as determined serious water shortages. Finishing as in the following case: (1) drum level is less than the normal level identifier; (2) low water alarms, alarm sound, lights light initiated; (3) the temperature of the superheated steam higher water vapor; (4) provided water is not normal, the flow rate is less than the water vapor; (5) the temperature of the water vapor discharged smoke increases.Free Chat
