Рамперные системы с водяным охлаждением и вибрацией

WCVG system is one of the newest technology for combustion of various solid fuels. With its water cooled grate area, higher furnace temperatures canbe obtained without damaging the system. System brings flexibility for using various kinds of solid fueland biomass. 

Also WCVG provides low maintenance costs and longer periodical service intervals due to its decreased mechanical hardware compared with similar systems.


The vibrating grate system has been developed by AKKAYA Inc. for high efficiency and reliable operation.


The system can be used with YSB, HYB, YHYB model steam boilers and YS, YHYBWB model hot water boilers. The size of the system can be selected and produced according to the boiler model and capacity.

Minimum 5 mm, maximum 50 mm sized solid fuel with a maximum 20-55% humidity (depending on the fuel structure) and low ash formation is recommended to be used in WCVG systems. Fuel is transferred from bunker on to the grate with the help of auger system, pneumatic conveying or hydraulic push pull systems.


Hydraulic system can only be used with bigger dimensioned fuels with very low friction forces. (mainly dry wood parts or dry coal parts). For the smaller fuels auger system is preferred. Pneumatic conveying system can be used for low density fuels (e.g. sunflower husk). System works with an air fan, injector system and an air lock.


At the top of the boiler furnace section, there are fuel reservoirs which collect and serve the fuel into the fuel bed. They are made of carbon steel. Also fuel level is controlled with level sensors on the fuel reservoir (bunker).


There are primary and secondary air fan& dampers mounted on the furnace of the boiler. Primary air used to control main combustion, to burn pure carbon content of the fuel. Secondary air is used to fire volatiles which appear during fuel heating Dampers are used to control the flow rate of the primary and secondary air.


In order to obtain vibration force on the water cooled grills for the fuel particles that fall down, vibration motors are used. Vibration motors are connected to grill with vibration profiles. Vibration profiles connected to chassis with special product leaf springs. Fuel bed i.e. water tube grill on the system consist of water tubes and membranes Vibration force makes the grill vibrate to provides the fall and travel of the fuel along the furnace. The vibration force is damped by using vibration tubes.


There are two level sensors mounted on the fuel reservoir, for minimum and maximum fuel level control.
In order to prevent fire risk in the boiler room a fire extinguisher system is used at the bunkers.
