A presente dissertação pretende demonstrar a possibilidade e mais-valia da integração da
energia solar térmica em processos de secagem industrial, no caso em concreto, na
secagem de Combustível Derivado de Resíduos (CDR) proveniente de resíduos urbanos
(RU), possibilitando a continuidade do funcionamento do secador industrial com exclusivo
recurso a Fontes de Energia Renovável (FER), garantindo assim que a qualidade do produto
que sofre secagem é também ela obtida não recorrendo a fontes de energia fóssil o que
contribui diretamente para a descarbonização da indústria e para o controlo de custos com o
combustível, bem como assegurar os princípios da sustentabilidade económica e ambiental
subjacente à atividade da empresa.
Sendo o sol uma fonte de energia de fácil obtenção, não poluente e inesgotável, a energia
solar, apresenta-se como a grande solução de independência energética, ainda que possa
ter que ser aliada a outras FER.
Esta fonte de energia tem particular interesse de utilização em processos industriais,
considerando que uma variedade de processos industriais exige calor em alguma parte do
seu processo.
Em Portugal, em 2019, o consumo total de energia final no setor industrial representou 29,5%
do consumo total de energia final em todos os setores, sendo que destes 14,6% do consumo
de energia final no setor industrial estão associados à produção de calor.
A utilização de energia térmica nos processos industriais ocorre a múltiplas temperaturas e
de acordo com a gama exigida assim se classifica a mesma em baixa, média ou alta. A
tecnologia mais adequada para obtenção de calor através de Energia Solar Térmica para
Processos Industriais (SHIP, no inglês) é determinada considerando a temperatura exigida
no processo industrial e a gama de temperaturas operacionais dos diferentes coletores
solares disponíveis no mercado.
De modo a garantir uma adequada integração da energia solar térmica num processo
industrial é essencial efetuar a avaliação da sua viabilidade técnica e económica.
This dissertation aims to validate the possibility and added value of integrating solar thermal energy in industrial drying processes, in the specific case, of the drying of Refuse Derived Fuel (RDF) from urban waste (UW). This enables the continued operation of the industrial dryer with exclusive use of Renewable Energy Sources (RES), thus ensuring that the quality of the product undergoing drying is also obtained without resorting to fossil energy sources, contributing directly to the decarbonization of the industry and to controlling fuel costs, as well as ensuring the principles of economic and environmental sustainability underlying the company's activity. Since the sun is a source of energy that is easy to obtain, non-polluting and inexhaustible, solar energy presents itself as the great solution for energy independence, even though it may have to be combined with another RES. This energy source has particular interest for use in industrial processes, considering that a variety of industrial processes require heat in some part of their process. In Portugal, total final energy consumption in the industrial sector represents 29.5% of total final energy consumption in all sectors, with 14% of final energy consumption in the industrial sector associated with heat production. The thermic energy used in industrial processes are manifold and classified according to the temperature range required, as low, medium or high. The most suitable technology for obtaining heat through Solar Heat for Industrial Processes (SHIP) is determined by considering the required temperature in the industrial process and the range of operating temperatures of the different solar collectors available on the market. In order to guarantee an adequate integration of solar thermal energy in an industrial process it is essential to evaluate its technical and economic viability.
