Utilisation of ash from heating boilers

Abstract

Power and heat production are playing an increasingly large role in society as the world continues to develop and becomes more reliant on electricity. Ash, being the main byproduct of burning solid fuels in the production of heat and electricity, creates a problem of how to deal with this potentially hazardous material. A key focus is to lower any risk of environmental damage and risk to human health and how it could subsequently be used beneficially. The goal of the study is to highlight possible further uses of ash as well as improve global utilisation. Firstly, the types of ash being produced will be looked at with regards to their generation and composition. Then compare how two different counties utilise the ash they produce and explore the possibility of techniques and technology regarding the use of ash is transferable between the two countries to improve the quantity and amount being reused while also looking at benefits and challenges that might arise. It will primarily be a literature review focusing on regulations set out by each country as well as the properties of the ash to provide a base level of knowledge regarding how has is currently being used. Within the study, several areas were able to be highlighted regarding ways India could learn from Finland’s example in terms of how the country is focused on becoming carbon neutral and as a result how Finland utilises its ash in multiple ways.
