Modernization and overhaul of pressure part in water and steam boilers, consists of:
additional shielding of furnace
replacement of the air heater with water heater
replacement of the cast iron water heater for steel water heater
additional water heater - economizer
For retrofitted boilers we produce:
steel water heater in place of cast iron one.
furnaceless water boiler BKW (economizer) in the exhaust system. BKW fits both water and steam boilers.
All our pressure parts have credentials of the Office of Technical Inspection.
The Water Heater is a heat exchanger, wherein the hot flue gas discharged from the boiler heats the water. It consists of a steel pipes in the form of coils. The use of steel water heater in place of cast iron ones reduce the resistance of the exhaust gas flow, improve the conditions of heat transfer and increase the efficiency of the boiler thus making whole boiler operations more fianancially viable.
Furnaceless Boiler Water BKW (economizer) is a device to control the temperature of the exhaust gases.
BKWs are placed in the flue gas ducts between main boiler and dedusting installation. Heating medium is flue gas. Devices are supplied with water which is fed to the boiler or from the outside circuit (tap water). They have independent from the boiler control, measuring devices and circulators.
Sections coils are made of boiler tubes and encased sheet metal. The whole installation is protected by a thermal insulation. The device reduces the exhaust gas temperature of 120°C to temperature set at the outlet.
Our BKW device is awarded Certificate of Conformity issued by UDT-CERT.
Power devices from 300kW to 3MW
Pressure - operating range from 0.4 to 3 MPa
Supply water temperature of 50°-70°C
Heated water temperature 150°C
Ability to work fully automatic
BKW devices are designed for water and steam boilers with a capacity of up to 50MW.
