Abstract

The thermal treatment of waste by incineration is considered an ultimate solution in order to get rid of waste properly by using the combustible properties of waste and transforming them into inert form and gaseous emission, with the main advantage of a huge reduction in mass and volume of treated waste, destruction of the dangerous components in waste, and obtaining green and clean energy from the exothermal reaction from the completed combustion process. In order to achieve the main goal of incineration, a good design, construction, supervision, and intensive operation and maintenance must be taken into account, especially for the small-scale incinerator. This research will deal with the green, innovative, and eco design and manufacturing technology of a 1-ton per batch municipal solid waste (MSW) incinerator. The concept design of the incinerator will focus on the design of the feeding process where only one batch of waste will be discharged into the combustion chamber at one time instead of the semi-feed process, as found in the conventional incinerator. This will ease the operation of the operator and reduce the operating cost. Moreover, the innovative design includes the redesign of combustion air injection into either the primary or secondary combustion chamber in order to achieve the 3Ts of combustion (time, temperature. and turbulence). This design can eliminate the use of an auxiliary burner in the primary combustion chamber. Rethinking the innovative design of using recirculation hot flue gas for preheating of wet garbage in order to pre-dry the waste before combustion is also taken into account. The manufacturing process of the wall composition as well as other parts of the incinerator are also examined.

Highlights

The disposal of municipal solid waste (MSW), which is the discard of matter from human activities, must be done in a proper manner in order to avoid the impact on the environment
Each batch is enough to partially burn for 10 to 15 minutes, the charging will start to feed the MSW in the chamber again. Advantage of this technique is to help the combustion to be taken place in a short time and can avoid the excess pollutants coming from the primary combustion chamber (PCC) to the secondary combustion chamber (SCC)
Waste will be charged in the PCC and will sit on the grating, which is made of cast iron, in order to sustain a high temperature during the combustion

Summary

Introduction

The disposal of municipal solid waste (MSW), which is the discard of matter from human activities, must be done in a proper manner in order to avoid the impact on the environment. Due to the small capacity of facilities, the burning of waste does not yield enough by-product energy to produce heat or electricity, which causes high operating cost since additional fuel is required to achieve a high destruction temperature [2]. With the strengthening emission standards nowadays, many onsite incinerators remain unused [3]. The objective of this work is to redesign and manufacturing of the Green, Eco, Innovative Design and Manufacturing technology of a 1ton per batch MSW in order to use the incinerator at the source of MSW generation. The operating batch time was about 6 to 8 hrs and needed only a one-time charge of MSW into the combustion chamber by using a dumping garbage truck. It was designed to achieve inexpensive operating costs but would be able to attain emission standards which would lead to a Green, Eco and Innovative small-scale MSW incinerator
