The session reviews the concept of heat and energy production, describing the most common units used, and methods to estimate heat demand at various scales. The concept of district heating systems and their development in several countries is presented, linked to their limitations and advantaged. Also, small scale pellets boilers are presented, and the general heat production in Finland and Sweden is presented and analysed. Finally, the biomass needs of several bioenergy plants are presented and compared as case examples.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\" id=\"S9Energyproduction-Objectives\">Objectives<\/h2>\n\n\n\n<p>The main objectives of this session are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>To review main factors related to energy production<\/li>\n\n\n\n<li>To understand the main issues related to the establishment of district heating systems<\/li>\n\n\n\n<li>To review methods to assess heat demand for a large city or community or at a domestic level<\/li>\n\n\n\n<li>To discuss the role of district heating systems, particularly in Northern Europe<\/li>\n<\/ul>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\" id=\"S9Energyproduction-Tools\">Tools<\/h2>\n\n\n\n<p>Forest Heat v2.0 [<a href=\"https:\/\/studentuef.sharepoint.com\/:f:\/r\/sites\/Biopro\/Shared%20Documents\/Supply%20and%20Energy%20Use%20of%20Lignocellulosic%20Biomass\/Materials\/Applications?csf=1&amp;web=1&amp;e=TAKuLZ\">xls<\/a>]<\/p>\n\n\n\n<p>Forest Heat is a simple planning and decision support tool for wood-based heating systems created by the Finnish Forest Research Institute (Metla).
