  • Bottom Ash-Boiler Slag Separate (Huang 1990)
    USER GUIDELINE FOR COAL BOTTOM ASH and BOILER SLAG IN GREEN INFRASTRUCTURE CONSTRUCTION by Principal Investigators: Craig H. Benson and Sabrina Bradshaw Decemeber 2011 Recycled Materials Resource Center University of Wisconsin-Madison Madison, WI 53706 USA USING COAL BOTTOM ASH AND BOILER SLAG IN GREEN INFRASTRUCTURE CONSTRUCTION INTRODUCTION This document provides a comprehensive overview of the engineering and construction properties of bottom ash and boiler slag for use in asphalt concrete aggregate, granular base, stabilized base aggregate, and embankment/backfill material. Studies addressing environmental concerns of using bottom ash and boiler slag, both industrial by-products, as construction materials are reviewed. Some case studies are presented to demonstrate successful applications of bottom ash and boiler slag. With the goal of advancing the use of bottom ash and boiler slag in construction application, references to resources and tools are made available. Coal bottom ash and boiler slag are coarse, granular, incombustible materials that are collected from the bottom of coal burning furnaces. The majority of coal bottom ash and boiler slag are produced at coal-fired electric utility generation stations, with some coming from coal-fired boilers or independent coal-burning electric generation facilities. The type of bottom ash or boiler slag produced depends on the type of coal-burning furnace. Bottom ash is produced as a result of burning coal in a dry bottom pulverized coal boiler. Unburned material from a dry bottom boiler consists of about 20 percent bottom ash Bottom ash is a porous, glassy, dark gray material with a grain size similar to that of sand or gravelly sand (Steam 1978).

  • Energy Recovery of Metallic Aluminium in MSWI Bottom Ash
    Energy recovery of metallic aluminium in MSWI bottom ash Different approaches to hydrogen production from MSWI bottom ash: A case study Rasmus Larsson Supervisor at Umeå University: Tekniska Högskolan Umeå Universitet Docent Thomas Wågberg EN1416 Examensarbete för civilingenjörsexamen i Department of Physics energiteknik, 30 hp, VT 2014 Supervisor at Umeå Energi AB EN1416 Thesis work for Master of Science in Energy Engineering, 30 ECTS, Spring 2014 Niklas Jakobsson Planning engineer Abstract Most of the wastes in Sweden end up in incinerator plants. These trashes are full of metals, especially aluminium, which will not oxidize, they can’t always be recycled and they will instead oxidize in water and leak hydrogen gas to its surrounding. Estimations calculate it could be an average potential of around 40-50 kWh/ton of burnt trash. Ignoring the imported trash, the national recovery potential of Sweden’s 4,3 million tonnes of trash would then be equal to 170- 220 GWh/year due to non-recyclable metals, which are currently going to temporary landfills. The requirements to harness this potential are technically simple, and can be achieved by a quick separation of the recyclables and the non- recyclables. This report will review the factors which increase the rate of reaction and study different ways of extracting the energy, by electrolysis, thermal treatment and mechanical mixing. This was done by taking small samples from the MSWI, owned by Umeå Energi AB, and putting them in small containers. While using the different methods, electrolysis, thermal treatment and mechanichal mixing, the amount of developed H2 gas over time was measured.

  • Ccr and Elg: a Joint Approach to Bottom Ash Management
    CCR AND ELG: White Paper A JOINT APPROACH TO ©2017 GAI Consultants By David Weakley II, PE BOTTOM ASH MANAGEMENT Assistant Engineering Manager GAI Consultants Abstract l While both the Coal Combustion Residual (CCR) Rule and the Effluent Limitations Guidelines (ELGs) were developed separately, there are several common elements shared between the two regulations. By considering both rules concurrently, a unified, cost-effective solution can be engineered and constructed. Implementation of CCR and ELG rules generally coincides with a facility’s National Pollution Discharge Elimination System (NPDES) Permit renewal schedule. Optimizing a station’s water balance by increasing water reuse/recycle and eliminating or reducing unnecessary wastewater streams can greatly reduce the capital expenditure requirements of environmental projects for CCR and ELG compliance. Achieving a zero liquid discharge (ZLD) bottom ash transport water system can be coupled with other station initiatives such as CCR leachate management and cooling tower blowdown management. Managing CCR landfills with respect to reducing leachate quantity and improving water quality can have significant effects on overall station compliance. Ash pond reconstruction (retrofit) or replacement activities can be considered to figure into the station’s overall environmental compliance Ash pond reconstruction plan. Retrofit projects considered are raising pond beds, relining, and (retrofit) or replacement footprint reduction while replacement projects could be geotubes, drag activities can be chains or tank based systems. considered to figure into the station’s This paper discusses methods and approaches to optimizing a coal fired overall environmental power station’s water balance, developing a ZLD system for bottom compliance plan. ash transport water, repurposing existing station ponds, and managing CCR solids.

  • Incineration Fly Ash and Its Treatment to Possible Utilization: a Review
    energies Review Incineration Fly Ash and Its Treatment to Possible Utilization: A Review Altaf Hussain Kanhar, Shaoqing Chen and Fei Wang * State Key Laboratory of Clean Energy Utilization, Zhejiang University, Hangzhou 310027, China; [email protected] (A.H.K.); [email protected] (S.C.) * Correspondence: [email protected]; Tel.: +86-571-87952628; Fax: +86-571-87952438 Received: 29 October 2020; Accepted: 9 December 2020; Published: 17 December 2020 Abstract: Incineration has gained popularity over landfill as a key solution for the reduction of massively increasing volumes of municipal solid waste (MSW) generation worldwide and in particular China. However, it is not the end solution. The disposal of the incineration residues, which are enriched with a wide range of heavy metals and soluble salts, has become a challenge for the environmental managers. The aim of this study was to review the increasing urbanization and its repercussion on waste generation in China; waste management options were compared for possible environmentally friendly considerations. Treatment techniques of incineration fly ash were discussed to determine the effectiveness of obtaining environmentally stable material, and, finally, possible applications of incineration fly ash for utilization were discussed based on identifying the processing suitability, performance and environmental impact of incineration fly ash for its applications. Keywords: municipal solid waste; incineration; fly ash; urbanization; heavy metals; treatment techniques 1. Introduction In 2016, around 2.01 billion tons of solid waste was generated worldwide. With increasing population, urban expansion and industrialization, the annual waste generation is expected to increase by 70% in the coming two decades [1]. Chinese urban expansion is increasing year by year and so is the generation of municipal solid waste.

The government is currently implementing policies to increase the usage of coal as fuel for electricity generation. At the same time, the dependency on gas will be reduced. In addition, coal power plants in Malaysia produce large amounts of industrial waste such as bottom ash which is collected in impoundment ponds (ash pond). However, millions of tons of coal ash (bottom ash) waste are collected in ponds near power plant stations. Since bottom ash has been classified as hazardous material that threatens the health and safety of human life, an innovative and sustainable solution has been introduced to reuse or recycle industrial waste such as coal bottom ash in concrete mixtures to create a greener and more sustainable world. Bottom ash has the potential to be used as concrete material to replace fine aggregates, coarse aggregates or both. Hence, this paper provides an overview of previous research which used bottom ash as fine aggregate replacement in conventional concrete. The workability, compressive strength, flexural strength, and sound absorption of bottom ash in concrete are reviewed. 1 Introduction Major environmental problems around the world are usually due to the disposal of waste materials such as industrial waste, construction waste, household waste and etc.

  • Management of Coal Combustion Wastes
    Management of coal combustion wastes Xing Zhang CCC/231 ISBN 978-92-9029-551-8 January 2014 copyright © IEA Clean Coal Centre Abstract It has been estimated that 780 Mt of coal combustion products (CCPs) were produced worldwide in 2010. Only about 53.5% were utilised, the rest went to storage or disposal sites. Disposal of coal combustion waste (CCW) on-site at a power plant may involve decades-long accumulation of waste, with hundreds of thousands, if not millions, of tonnes of dry ash or wet ash slurry being stored. In December 2008, a coal combustion waste pond in Kingston, Tennessee, USA burst. Over 4 million cubic metres of ash sludge poured out, burying houses and rivers in tonnes of toxic waste. Clean-up is expected to continue into 2014 and will cost $1.2 billion. The incident drew worldwide attention to the risk of CCW disposal. This caused a number of countries to review CCW management methods and regulations. The report begins by outlining the physical and chemical characteristics of the different type of ashes generated in a coal-fired power plant. The amounts of CCPs produced and regulations on CCW management in selected countries have been compiled. The CCW disposal methods are then discussed. Finally, the potential environmental impacts and human health risks of CCW disposal, together with the methods used to prevent them, are reviewed.
