hog insinerators

Finish

All equipment shall be painted with a coat of zinc rich primer and two coats of high temperature heat resistant

polyurethane type paint. All painted surfaces shall be prepared by either steel shot cleaning or sand blasting.

Identification and Name Plates

Identification and name plates containing the manufacturer’s name, model number, serial number, and other pertinent

information shall be securely fastened to the unit in readily visible locations.

Fuel Type and Tank

All burners shall be fuel oil (diesel) fired. For all incinerators fitted with fuel oil (diesel) type burners, the

bidder shall supply and install 1000 litres steel tank and all the necessary piping and fittings and initial supply of

1000 litres fuel oil. Where existing fuel is found to be still in good condition from site inspection, contractors must

use existing tanks and therefore must clearly specify in their bids of such usage. The tank shall be positioned at

least 2 meters above ground on steel frame next to the incinerator shed. Fuel delivery to incinerator burners shall be

by gravity feed. The tank should be fitted with a drain plug as standard.

1. Post – combustion chamber:

Medical waste incinerator

Standard requirement:

The medical incinerator should meet the European standards 2000/76/EC.

Basic requirements:

1-Capacity 100kg/hr.

2-Work for 24 hours.

3-Unit should have enough combustion room consists of two combustion chambers (mounted vertically)

4- Unit should supply with control methods for air entry to the primary and secondary chambers and hence incineration

of the waste is accomplished.

5-The unit charging is done automatically and have an option to be done manually.

6-The ash removal is done automatically and have an option to be done manually

7-The unit should have a dry filtering unit.

8-The unit should be controlled from the control panel.

control panel :

Should show different tasks of operation using (PLC)

-Temperature in combustion chamber

-time of operation and combustion.

-different pressures.

-amount of air in combustion.

-efficiency indicator.

-emergency system in case of increasing pressure or temperature.

f- Time for gas passing:

Minimum time required for passing to combustion chamber for oxidizing 0.5 seconds at 800 degree Celsius .

1- design details:

A-primary combustion chamber:

Oxidize all waste to combustion residuals and temperature not less than 800 degree Celsius.

b- Secondary chamber:

Continue combusting combustion gas residuals and hanging particles using additional burner temperature not less than

1100 degree Celsius and this conditions is reached by harmonizing between temperature and time of passage to ensure

adequate oxidizing supplying enough air to ensure turbulence of gas all the time this is controlled from control panel.
