Compatibility of Compacted Soils with Municipal Waste Combustion Ash Leachates
Hydraulic conductivity values for three compacted soils were used as indices of compatibility of the soils with two municipal waste combustion (MWC) ash leachates. Specimens of the three soils were compacted to 90% of proctor compaction (ASTM D 693) in double-ring permeameters and permeated first with water (0.005 N CaSO4) and then with MWC ash leachate. The hydraulic conductivity values of the ...

Continuous Monitoring System Performance Through Electronic Systems
Hazardous waste combustion facilities are already familiar with most of the recordkeeping requirements included in 40 CFR 63, Subpart EEE due to previous compliance with the Boiler and Industrial Furnace (BIF) rule. The NESHAP, however, requires semi-annual continuous monitoring system (CMS) performance reporting that was not previously required under BIF. These provisions specify numerous ...

Focus Bioenergy No 6 2004: Waste - a source of energy of growing significance
We have to use the earth’s resources sparingly. Waste products that society generates can be recycled or used as a source of energy. Heat and electricity from waste combustion and biogas from digestion contribute some 8 TWh annually in Sweden. Waste stands for about 2 percent of used fuels in Swedish district heating. The importance of waste will rise rapidly in the near future. The potential for ...

Effects of combustion efficiency on an Otto cycle
This paper explains how the combustion efficiency influence the performance of an irreversible Otto cycle under conditions of varying fuel-air ratio. The irreversibility of Otto cycle comes exclusively from the expansion and compression processes. It is assumed that some fraction of the fuel's chemical energy cannot be fully released inside the engine because of incomplete combustion. Amount of ...

Plasma Arc Waste Destruction System (PAWDS) - A novel approach to waste elimination aboard ships
The Plasma Arc Waste Destruction System (PAWDS) uses plasma energy, with temperatures over 5,000 oC, to rapidly and efficiently destroy combustible waste aboard ships. PAWDS has proven itself to be a viable alternative to traditional incinerators. In September 2003, Carnival Cruise Lines were the first to install a PAWDS aboard their 2,056 passenger (plus 1,000 crew members) capacity, M/S ...

Proton Power 25m3 DIY Syngas Storage
Based in Tennessee USA Proton Power Inc. (PPI) was founded by 2 remarkable entrepreneurs with previous successes in such diverse areas as aircraft brakes and neutron absorbers (don’t ask!). With this kind of history we knew their requirement was going to be beyond our usual scope. We weren’t wrong - they requested a 25m3 Base gas holder in which to store a syngas mixture with high ...

Measuring Gases Produced by Waste Gasification to Improve Control and Efficiency
Waste gasification is a type of waste to energy process where waste material is used as a fuel to create heat, electricity or other chemical products. Specifically, in waste gasification, the waste material is decomposed in such a way to produce gaseous products, often known as syngas, a combination of hydrogen, carbon monoxide and some carbon dioxide.Conventional incineration uses heat and ...

Choosing The Right Wood Charcoal Machine
Should your business provides extensive wood scraps and waste, you might like to take a look at a wood charcoal machine. These appliances transform wood waste into charcoal providing another avenue of revenue for your personal business. The problem for most of us comes if they have to find the right wood charcoal manufacturing machine. There are a variety of options in the marketplace, but not ...

A STIEFEL project UTO Uvrier case study
The waste incineration plant UTO Uvrier is situated in the south western part of Switzerland. The Association which controls the plant was established in 1969 and treats waste from 44 municipalities with a combined population of 170,000 inhabitants. The principal task of UTO Uvrier is the thermal heat recovery from urban and industrial waste. Apart from this, UTO also treats other types of waste ...

Waste co-incineration in the European Community, is the sky the limit?
The co-combustion of waste in industrial furnaces -co-incineration- attracts considerable interest in the European Community, because of the combination of perceived business incentives, regulatory developments, and the slate of available technological options. It was found, however, that EU-regulation developed to ensure safe and environmentally acceptable processing of waste represents a clear ...

Monitoring of garbage chutes - Case Study
Application Waste recycling in incineration plants starts with the delivery and incineration of waste. The waste reaches the combustion chamber via a falling chute, which is followed by a hydraulic feed device. To guarantee a constant incineration process, the falling chute has to be fi lled constantly. The „high“ and „low“ limit values should be detected and alarmed. The ...

Incineration
Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...

An economic feasibility model for ash use in flowable fill with integration of logistics and contaminant leaching factors
Encasement of utility cables and pipes in flowable fill monoliths formed in trenches requires the use of materials that satisfy both strength and contaminant leachability limits. Coal combustion ash is often readily available for use in flowable fill construction. The use of ash in desirably large quantities, calls for the determination and selection of the maximum ash mix fraction that meets ...

Radiocarbon measurement of fossil CO2 emissions from waste incineration plants: A monitoring tool for CO2 trading in Denmark and Sweden
In several countries, an increasing share of renewable energy comes from waste incineration. Due to the content of fossil carbon in combustible waste, the fossil CO2 constitute a considerable share of the total CO2 emissions from combustion of municipal waste. The National governments in Denmark and Sweden have decided to include the emissions of fossil CO2 from municipal waste incineration ...

Main uses of wood pellets
As a new type of energy, wood pellet fuel is slowly affecting people's lives. It is now mainly used in three aspects: 1. Small kilns are used to heat the home and supply life energy. This kind of application is mainly based on biomass pellet fuel, which is used more in Northern Europe. Because there is no related product development in China, its application is almost blank. 2. The unprocessed ...
