2.1. Flexibility

Syngas

Waste FlexibilityMainly MSW or RDF with other waste

This system has high waste flexibility and

requires no pre-treatment.

No pre-treatment

High temperature gasification (>1,800 C)

Double damper system (max. 800 mm)

CfD EligibleContinuous syngas measuring

Stable combustion

Approx. 5.9 MJ/m3N based on 9.1 MJ/kg-waste

3.2.1. Environmental Friendly

(1) Low Emissions

Syngas combustion

(homogeneous combustion) 3Ts (Time, Temperature, turbulence)

Lower emissions such as PCDD/DFs,

HCl and SO2 have positive impact

for achieving permissions.

(2) Energy and Material Recovery from Waste

- Recycling material from waste without further post- treatment

- Minimizing non-recyclables and landfill amount- Contributing to “Circular Society” or “Zero Waste”


11/19

3.3.1. Sustainability - Energy from Waste -

- Horizontal Boiler

- η : >28%

(11 MJ/kg, 10t/h x 2 lines)

- Dust Removal:

Rapping system

Shower Cleaning

Soot Blower for Economizer

Lower maintenance problems

- Combustion chamber is also

the part of the boiler

3.4.5. Reliability

(1) Technical Reliability

Should have commercial plants, not demonstration

Well proven Should know “WASTE”

(2) Company Reliability

Should have strong financial condition

Capability for EPC

Single responsibility

=> Bankable technology

(3) Operation support

Operating experience

Well-developed supporting system

3.4.5. Reliability - Operating Support -

(1) PlantPAD

Monitored operating condition remotely Inspection data is recorded

Checking operating data

- ITV

- Historical trend data

- On-time operating condition

easier maintenance management

(2) Predictive Operating

Many operating records can predict the operating conditions.

Several parameters are picked up for predictive operation.

Less operation load

These supporting system lead easier “O&M” of gasification technology

4. Summary

NSENGI Group has a capability to provide various solutions for clients.

(gasification, incineration and others)

The Direct Melting System can achieve both the energy and material

recovery from waste without any pre- and post treatment.

Driving factors of waste gasification for deployment are

(1) Flexibility of waste

(2) Environmental Friendly

(3) Sustainability (Energy and Material recovery)

(4) Reliability

Especially, our waste flexibility have great possibility to contribute to

“Circular Society” and to improve feasibility of the project.
