5. g the operating mode of the boiler as well as the ash content of the raw fuel ATTENTION e After each cleaning procedure the boiler should be checked out the correct attachment of the element the air tightness of the lids and the boiler s functionality e At the end of the heating season it is necessary to perform thorough ash cleaning of the boiler because the mineral ash acts as corrosive reagent and reduces the reliability of the boiler It is recommended to take away of the fuel hopper any pellets of other fuel if utilized as the pellets could absorb moisture from the ambient air and cause clogging of the fuel transport auger issues with the ignition etc The above depicted ash cleaning procedure is OBLIGATORY In case that the ash cleaning and boiler s maintenance procedures are not followed it is possible to decrease the efficiency and performance reliability of the boiler even operation failure could be achieved for example clogging of the ash cleaning mechanism flue gas fan blockage etc p 14 14
6. th the pipes of the heat exchanger EXPLANATION it is recommended to position the ash hopper in a position which will allow easy collecting of the ash residue The next step is to clean the ash and char residue deposited in the burner ATTENTION before lifting up the cover of the burner it is necessary to make a safety check 1 e to verify that the temperature of the burner s details is low enough to handle and continue with the manipulations It is strongly recommended to get measures for self protection Figure 2 11 Lift of the burner s arc lid EXPLANATION the lid of the burner is freely mounted and no fixing items are used It is positioned by special locking pins fixed to the lower part of the burner in its front side p 10 14 Figure 2 12 Ash and char cleaning procedure of the material laid on the burner s grate Figure 2 13 Brushing and cleaning the ash residue and any other char remaining particles on the burner s grate After the burner s grate has been thoroughly cleaned it is necessary to clean the ash beneath the grate p 11 14 EXPLANATION the burner s grate is detached by lifting and alongside pulling action It is possible to have difficulties when detaching the grate due to the deposited ash and eventually any thermal deformation of the details It is necessary to take care at the grate removal procedure and to keep the ash grating element not damaged it is not necessary to appl
7. xchanging surfaces as well and other surfaces that are in direct contact with the flue gases the burner the flue gas fan etc The ash residue quantity collected in the main ash hopper positioned in the combustion chamber should be cleared periodically considering the operating mode of the boiler as well as the fuel quality The practice shows that according to the ash in that hopper should be cleaned thrown away periodically between one and five days the fuel should cover the requirements depicted in the user manual of the boiler It is advisable to clean the convective part of the heat exchanger by utilizing the applied the specialized lever it should be plugged in the profiled orifice and swing the lever in both direction several times which actually will activate the semi mechanized cleaning system of the boiler The total ash cleaning procedure should be performed once per month advisably but not more that two months period of hot water boiler s operation The period between ash cleaning of the boiler should be clarified at practice as it depends mainly on the fuel quality 2 Hot water boiler ash cleaning procedure ATTENTION it is strongly recommended to have self protection utilize gloves protection glassed and appropriate clothing as the risk of injuries is high at high temperatures of the surfaces in the combustion chamber of the unit The following sections will describe the cleaning ash cl
