Castable high quality refractory liner and incinerator shell


The daily oil tank of capacity 1,800 litres and size 1220x1220x1220mm pressed steel tank top will be placed 2.5 metres high above ground level on a steel stand, firmly secured on the ground and also the steel members to be straightened.  The oil tank will have an oil level indicator, access manhole, washout, flow, toaster and sockets connections and gate valves.

The interconnecting pipe of 50mm diameter between both tanks will be class’C’ black mild steel pipe, complete with a 50mm diameter strainer.  The burner fuel supply pipe from the daily tank will likely be a 25mm diameter class’C’ black mild steel.

The following will also be provided
•    Access ladder into the Peak of the tank
•    Vent pipe
•    25mm diameter flame valve
•    Air receiver
•    heating tap across the burner supply pipe, 25mm diameter

The burner supply pipe will have 25mm thick fibre glass insulation and finished with gauge 20SWG galvanised steel sheet.

The tenderer will supply all the needed controls for proper safety and satisfactory working of the installation.

1.1.1    BURNER

The burner will be suitable for 35 sec redwood No. 1 scale gas oil.  It will be robust in construction and be manufactured from cast iron or other appropriate materials complete with mounting plates.  The burner will have an adequate supply of oil which can spark and burn in a secure manner.  Adequate supply shall be offered to prevent any solid matter in the petroleum, or any matter that may separate out from the petroleum from damaging any components or chocking of any orifices or valves.  The free filtering area ought to be sufficient to make certain that the filter does not need dismantling for cleaning more frequently than once a year. The burner will have flame supervision by photo-electric mobile with synchronous chain control for automatic start up, running and shut-down of the burner.

The burner will have all the essential controls e.g.Solenoid valves, ignition controls, photo electric cell fuel safety controllers, low pressure gas distribution cut-off etc..

The burner will conform to BS 799: component 3 and 6 1981 or any other applicable British standard.The burner will be as NU-WAY versions or equivalent and approved.

1.1.2    CONTROLS

The incineration will operate in an automatic manner with all the essential controls.  These controllers are to include safety elements like flame failure unit, pilot lamps, fuses, starters, overload contactors, ON and OFF switches for burners and fans, combustion chamber temperature indicators for secondary and primary chambers etc..

I)     Electric ignition switch’ON’ before the oil is provided
•    25mm diameter top capacity strainer
Ii)    Delayed return to re-start position to allow purging
Vi)    Photo electrical protective mobile as flame failure device.

The controllers shall be mounted on appropriate control panel to be set up at a position easy to read and control from the charging side of the incineration.

The control panel will be manufactured from anodized, 16SWG, mild steel sheet.

The incineration will have chimney, castable high quality refractory lining and incineration shell, perforated blind for the main and secondary combustion chambers and air circulation system.
Iii)    Re-start after temporary electrical supply failure
•    Main and secondary burners and fans
•    FD fan
•    Fully wired controller panel

The bulk oil storage tank will have a capacity of 10,200 litres and be placed at 0.5m above ground on a firm concrete cradle, complete with all the following:-
•    Manhole cover whole with a gasket
•    Ash door
•    Dip stick
V)    Red sign light on control panel to indicate safety lock out

The control panel shall be fabricated from anodized, 16SWG, mild steel sheet.
