Batch Loading Gasification Incinerator

Introduction

Batch loading eliminates the need for an operator to attend machine operation as with conventional incinerators. Exhaust gas is provided sufficient temperature and retention time to ensure that it is smoke- and odor-free.

Structure

This equipment comprises a combustion chamber, reactor, chimney and accessory units, and operates as follows. Roughly 30% of the air needed for combustion is supplied to the combustion chamber where it is gasified and burned for baking the waste that is to be incinerated. The remaining air is then supplied to the reactor which is then heated by a burner to the temperature for smoke-free combustion. After the waste is completely burned, it is then discharged from the chimney. Also, the windspeed inside the combustion chamber is kept to a minimum to prevent ashes from scattering.

The following waste can be incinerated:

1) Paper, wood, cloth, etc.   (calorific value: 3000 to 4400 kcal/kg)

2) Plastic scrap (calorific value: 4500 to 11000 kcal/kg)

3) Styrol foam scrap (calorific value: 10500 kcal/kg)

4) Rubber scrap (calorific value: 9000 kcal/kg)

5) Waste oil, paint, etc. (calorific value: 3000 to 7000 kcal/kg)

Features

l) Batch loading, fully automated operation.  Just press the START switch, and rubbish 
   is completely incinerated, eliminating the need for an attendant operator.

2) As sufficient temperature and retention time is provided, exhaust gas is smoke- and odor-free.

3) The equipment is built to minimize the generation of soot and dust, eliminating the need for dust-collectors .

4) Various types of rubbish can be burned together.

5) The seamless single-wall structure is made of non-standard fire-proof materials, making it highly durable. Also, the equipment is designed in a simple structure to facilitate maintenance, inspection and repair.

6) Induction blowers are no longer required, allowing power consumption and noise to be kept to low levels.

7) A rigid combustion system saves installation space.
