Boiler water-heating low-temperature KVVD-0,63 is a combined water-tube-boiler boiler of 630 kW capacity with the forced circulation of heat-carrier through the boiler.<\/strong><\/p>\n

Designed for heating and hot water supply without direct water collection.<\/p>\n

Designed for use on natural gas or light liquid fuel and designed for hot water production with a pressure of up to 4 kgf \/ cm2 (ATI) and a temperature of up to 95 \u00b0 C.<\/p>\n

The boiler can operate in automatic mode offline.<\/p>\n

The boiler consists of the following parts and units:<\/p>\n

– Boiler body of oval shape;<\/p>\n

– Welded to the body of the front and rear tubular boards;<\/p>\n

– Furnace tubes welded in the upper parts of the anterior and rear tubular boards;<\/p>\n

– Furnace chamber, which includes a hot tub and an on-screen system with circular tubular boards. In a fire chamber between the rear and front water ring cells, 36 screened tubes are divided, separated by 12 three-way beams. Water is fed to the back chamber, passes into the anterior chamber, so back and back to the front (ie, 3 turns), where through 12 openings comes into the water volume of the boiler body;<\/p>\n

– Door of the boiler, which has a rotary chamber of flue gases from a refractory lining;<\/p>\n

– Burners, which are attached to the flange door of the boiler.<\/p>\n

The KVVD-0.63Gn boiler is equipped with the RS-70 block fan burner manufactured by Riello S.p.A (Italy) and the electronic automatics of RV \/ t also manufactured by Riello S.p.A (Italy), certified in Ukraine.<\/p>\n

The flame of the burner enters the annular screen chamber, which is closed in the bottom part. The camera works with excess pressure of flue gases, which come in 2 fire tubes, then into a rotary chamber and on flue pipes in the smoke box located at the rear of the boiler. From the smoke box, the gases are evacuated to the chimney and into the atmosphere.<\/p>\n

The gas path of the boiler is located at the work of the burner under excessive pressure relative to the atmosphere. In flue pipes due to the installed turbulators, flue gases move vortex, due to which improves convective heat exchange.
\nThe thermal insulation of the boiler body is made of mineral wool mats and is enclosed in a sheath.
\nThe boiler is equipped with a control panel that allows the boiler to be operated automatically without any other personnel. The control panel allows you to connect an electronic device that can operate the boiler mode, taking into account the temperature of the outside air.<\/p>\n
