Hot and hot water boiler

Power steam

Hot water and hot water boilers:

All hot water boilers manufactured by Bohar Niro company are produced according to BS855 international standards and SIRI7911 national standards, which are under the supervision of quality inspection company and The Iranian standard is designed and manufactured and provided with a quality control plate and standard mark. 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. Spa boiler capacity from 150000Kcal to 5000000kcal/h in 2 pass and 3 pass with working pressure of 6. It is 8 and 10 times.

The maximum allowed water temperature of the spa boiler is 90 degrees Celsius and the hot water boiler is 130 degrees Celsius. It is of type 17155 17mn4-DIN and heat tubes are of type S35.8-DIN17175. Boiler design is done with a maximum pressure of 1/1 times the working pressure and hydrostatic test is done with a pressure of 1/5 times the design pressure. All welding lines are tested according to national and international standards by the representatives of the Iranian Standards and Industrial Research Department, which include ultrasonic radiography of penetrating and hydrostatic materials. Descaling two hand hole valves are installed in the boiler.

The electrodes used for penetration and finishing welding are E6010 and E7018 in accordance with the relevant WPS and PQR.

All the flanges used are of the standard PN16 type. The design and construction of boiler doors are hinged and open, which makes possible boiler repairs easier. - The body of the boiler is assembled on a resistant chassis that easily withstands the shocks caused by the weight of the boiler and does not require a concrete foundation. - The exhaust outlet has a thermometer to show the outlet temperature and a smoke thermostat to set the temperature at a certain temperature in order to prevent energy loss and ensure the proper operation of the boiler and burner.
