Abstract
U ovom će se radu pobliže istražiti problem zbrinjavanja pepela koji nastaje u pogonima za proizvodnju energije. Proučavat će se isključivo pepeo dobiven kao nusproizvod u energanama koje za sirovinu koriste drvnu biomasu. Objasnit će se što je biomasa, njezine vrste te prednosti i nedostaci koji se javljaju tijekom njezine upotrebe. Biomasa ima nedvojbeno velik potencijal u proizvodnji energije te je trend njezinog korištenja u stalnom prirastu. Prirast broja takvih energana prati i prirast količine ostataka od izgaranja. Jedan od tih ostataka koji ostaju nakon upotrebe biomase u svrhu proizvodnje energije je pepeo. Cijene odlaganja ostatka odnosno pepela također rastu pa se proučava mogućnost njegovog korištenja. Analizirat će se mogućnost korištenja pepela u industrijske svrhe. U ovom radu naglasak se stavlja na proučavanje mogućih načina korištenja pepela u betonskoj industriji. U sklopu eksperimentalnog rada provest će se ispitivanje, tj. mjerenje skupljanja uslijed sušenja na uzorcima betona u kojima će dio cementa biti zamijenjen pepelom od izgaranja drva. Također će se izraditi uzorci za praćenje svojstava betona tijekom očvršćivanja primjenom nerazorne metode – ultrazvuka. Na betonskim uzorcima također će se ispitivati tlačna čvrstoća, kapilarno upijanje te poroznost.
Abstract (english)
This paper investigates the problem of ash disposal arising in power generation plants. Only ash produced as a by-product in energy-generating plants using wood biomass will be studied. The term biomass will be explained, its types, and the advantages and disadvantages that occur during its use. Biomass has undoubtedly great potential in energy production and the trend of its use is steadily increasing. An increasing number of such plants is accompanied by an increase in the amount of residues left. One of the by-products produced by wood biomass power plants is ash. As the prices of managing such ash are also increasing, its potential applications are being studied. In this paper, the possibility of using ashes for industrial purposes will be analyzed. This paper is focused on studying possible ways of using ash in the concrete industry. As part of the experimental work, testing will be carried out on concrete samples where some of the cement will be replaced by wood biomass ash. Also, samples will be developed to monitor the properties of concrete during its hardening using a non-obstructive method - ultrasonic. Concrete samples will also be tested for compressive strength, capillary absorption and porosity.
