Boiler structural profile? CWNS1.4-85 / 65-Q (Y) Series Automatic fuel gas pressure hot water boiler for shell type three return, all wet back structure. The fuel in the combustion furnace positive pressure, high-temperature furnace flue gas along the back through the combustion chamber back into the first flue tubes, the oppressive smoke box before turning 180 degrees into the second bundle, after the convection heat transfer into the atmosphere. As heating, domestic water, providing endless power production with heat. We use the center symmetrical design, the design capacity of the three return structure of a large three-pass pressure hot water boiler. The greatest feature of this boiler: All pressure parts and drum central symmetry, boiler all wet back structure, with great inner cylinder and eccentric firebox structure, which facilitates expansion sufficient radiation heating surface. Convection heating surface is composed of three second return and the return of the bundle. Before returning combustion chamber pipe connected to the board using furnace, combustion chamber back to the tube plate using flat head tube plate. The second and third backhaul backhaul turning smoke chamber where the smoke box before, this a tobacco smoke temperature has been below 500 ℃. Therefore, before the smoke box structure fire-resistant insulation materials lighter shaped structure. After the smoke chamber flue gas outlet is disposed along the longitudinal axis of the barrel, not only shorten the length of the furnace, and also avoid the chimney in the direction perpendicular to the longitudinal axis of the cylinder, boiler condensate corrosion in the boiler starts to stop. This boiler is designed primarily consider the principle of boiler maintenance and stability. Mixing water in the boiler return means import settings, return to scour smoke tube bundles, then the contact furnace, furnace to improve the return water temperature exposure. Avoid boiling phenomenon of local produce. Kono horizontal condensing pressure hot water boiler corrugated furnace, threaded pipe, flat head tube sheet automatic welding process and greatly enhance the efficiency and service life, and safety performance of the boiler. Corrugated furnace features: 1, increase the radiation heat transfer area, improve thermal efficiency. 2, quasi-rigid structure becomes subject to an elastic structure, effectively eliminate stress. 3, high fuel burn efficiency, ensuring fuel burn sufficiently. Threaded pipe Features: 1, the optimization of the convective heat transfer, increasing the gas velocity, heat transfer speed is equivalent to the amount of threaded pipe ordinary cigarette tube 1.7-1.8 times. 2, threaded pipe smoke erosion by high speed, easy to knot gray, played the role of self-cleaning. 3, optimize the structure, reducing thermal stress. Flat head tube plate features: 1, the tube plate with flat head, pressure hot water boiler pressure components, reducing stress, solve the problem of tube sheet cracks. 2, completely changed the atmospheric heat boiler tube plate fillet welding methods to ensure the long life of the boiler. 2, before the smoke box and tube plate with anti-high temperature, strong anti-corrosion coating technology process, eliminating corrosion phenomena around smoke box, tube panels. Performance introduction boiler design, manufacture and testing according to JB / T7985─2002 "small boilers and pressure hot water boiler technology" and JB / T standards of production, the test, excellent quality. Flue gas flow using water-jacketed three return fire arrangement, all butt welding wet - back structure, large heating area. Corrugated gall bladder (or straight furnace), firebox asymmetric eccentric structure, the convection section inserted turbolator, optimization components. Configuring quality imported burner (low NOx burner), the flue gas harmful ingredients below the national standard (NOx emissions below 400mg / m3), are environmentally friendly products. Burning completely, low noise, safety and efficiency, and environmental indicators are in line with national requirements. Exhaust port can be configured condensing heat exchanger (optional), condensation of water vapor in the flue gas to absorb latent heat of condensation, thus improving the thermal efficiency of the boiler. Boiler and air is turned on, the configuration expansion tank, run at atmospheric pressure, no security risks. Boiler can be used with advanced touch-screen computer controller and digital computer controller, the controller has a timing control, work record, detection and alarm functions, and additional time lock manufacturers. To achieve automatic control of boiler operation, the return water temperature automatically adjust the boiler automatic ignition starts, with a variety of alarm interlock device to protect the boilers efficient, safe and reliable operation, installation and use more convenient. Perfect design, elegant, stylish, compact structure, beautiful appearance, overall quick shipment.
