A Possibility of Functioning Biogas Plant at a Poultry Farm

Abstract

The biogas production constitutes one of renewable energy sources (RES). In addition, wastes are preferred for energy production. In the case of some wastes, e.g. poultry manure, it is difficult to conduct anaerobic digestion in monofermentation. The aim of this work was to plan the biogas plant, in which the main substrate is the waste from a poultry farm. The scope of work included: preparation of a biogas plant technological project, determining the amount of biogas and methane that can be produced annually on the example of the selected poultry farm, performing the energy and financial calculations for the current conditions prevailing on the renewable energy market in Poland. The installation project assumed the location of a biogas plant at an existing poultry farm-the source of the substrate. The micro-biogas plant includes a fermentation tank with a capacity of 500 m 3 and storage of digestate pulp with a capacity of 700 m 3. The assumed power biogas plant will generate 112 kW of electricity and 120 kW of heat. The installation will operate in a single-stage mesophilic technology (39 ºC), which will avoid incurring additional costs related to heating and the construction of additional fermentation tanks. The use of poultry manure by anaerobic digestion provides benefits through biogas technology. It is necessary to examine the technology in terms of biogas production, which is carried out under better sanitary and environmental conditions. This work was undertaken to investigate the environmentally friendly removal of poultry manure through biogas technology to obtain the best economic effect, and employ it further, e.g. as a fertilizer.

Loss of Energy and Economic Potential of a Biogas Plant Fed with Cow Manure due to Storage Time

“…Another solution that brings measurable profits is the construction of a local biogas plant with a capacity of 250-500 kW and use of other waste streams [76,[120][121][122][123]. In the analyzed case, it would be an installation intended for a dozen local farmers (up to 10 km from the installation) and waste streams other than manure.…”

Emission Models for Selected Harmful Substances Emitted During Low-Temperature Combustion of Wood Pellets

“…Many of the combustion products have a negative impact on the human organism and the environment [Ciupek et al 2019b]. Top research works in the area of harmful emissions analyze the energy system of a heating device as a technical object interacting with the environment and the human through its thermal parameters (heating power) but also harmful emissions [Janczak et al 2019;Judt et al 2020;Chłopek et al 2021]. In [Ciupek et al 2019a;Ciupek 2019], in reference to phenomenological thermodynamics, a solid fuel heater/furnace is perceived as a closed thermodynamic system (within the balance boundary established by the researcher) that is non-uniform and of heavy environmental impact (outside the balance boundary) depending on the operating parameters used by the researcher and the parameters of the fuel.…”
