WCVG – Vibrating Grate System


Prominent Features

• WCVG is one of the newest technologies used in the combustion of various types of solid fuels.

• With the water cooled grate area, high hearth temperatures can be reached without damaging the system. The system provides flexibility in burning a wide range of solid fuels and biomass types.

• The WCVG system, which has a more simple mechanical equipment, has advantages such as low maintenance costs and the need for periodic maintenance in less frequent intervals compared to similar systems.

• Water-cooled vibrating grate system was developed by AKKAYA Inc to ensure high efficiency and safe operation.

• WCVG system can be used with YSB and YHYB model steam boilers and YS, YHYBWB model hot water boilers.

• Grates are sized and produced in accordance with the selected boiler model and capacity.

• It is recommended to use solid fuels with minimum 5 mm, maximum 50 mm dimensions, low ash and slag making capability and, depending on the structure, with 20% – 55% moisture in WCVG systems.

• Fuel is transferred from the bunker to the grate via auger, pneumatic conveyor or hydraulic thrust mechanism. There are primary and secondary air fans and dampers in the furnace of the boiler.

• Shipped with long-lasting insulation that minimizes heat losses.

• Production in accordance with EN12952 and PED2014 / 68 CE directives.

• Welding check of our boilers is carried out with non-destructive testing (NDT) within the scope and ratios specified in EN 12952-6.

• Our welded productions are carried out by certified welders according to approved WPS and WPQRs. MIG-MAG and SMAW welding techniques are applied during production in accordance with the norms.

• They are manufactured by using high quality, certified boiler sheet and seamless boiler tubes in accordance with standard requirements.
