Horizontal boiler
All boilers manufactured by Bokar Niro company are produced according to international standards BS2790 and national standard 2231, which are designed and manufactured under the supervision of Iran Quality and Standard Inspection Company and are provided with a quality control plate and a standard mark. will be Manufacturing system in two ways: wet back and dry back with working pressure 6. It is made 8 and 10 times. The capacity of steam boilers is from 100 kg/h to 10000 kg/h and the design temperature is 250 degrees Celsius.
The installation of steam boilers with manholes and numerous handholes allows access to the surface of the tubes and the furnace, which makes it possible to service the deposit. It makes disassembly and repair easy for the consumer. The design and construction of all boilers is based on the plans approved by the inspection company, which are provided to this company with the latest revisions by design experts. The front and rear valves make it easy to visit, service and repair the boiler and reduce the long duration of the related operations. Due to the proximity of the pipe sections to the furnace, it is possible to easily inspect, service and repair the furnace and tubes. The steels used in the construction of the furnace shell and boiler grids are 17155 17mn4-DIN and S135.8-DIN17175 and heat tubes are A516GR70. equal to the design pressure of the hydrostatic test.
All welding lines are tested according to national and international standards by representatives of Iran's Standards and Industrial Research Department, which include ultrasonic radiography.
Penetrating and hydrostatic materials. All welders have been tested for welding qualification according to EN 7-287 standard and have a welding qualification certificate from the most reliable inspection and testing centers under the full supervision of the factory's quality control unit. The electrodes used for penetration and complementary welding are E6010 and E7018, which are used in accordance with the relevant WPS and PQR. All the flanges used are of standard PN16 type. The design and construction of the boiler doors are hinged and openable, which makes possible boiler repairs easier. The doors are insulated with cement refractory concrete of Fond and French type and special chamotte. Proper insulation by stone wool and aluminum or steel cover according to the buyer's request prevents heat loss and while protecting the boiler against moisture and all external factors adds to the beauty of the installation site. The parts of the electrical panel and controls are selected from the best type and have a high efficiency and reliability factor, and the presence of pressure control switches and safety valves, as well as water fountain glass for visual control and siren maximizes the safety risk of the device.
