Biomass heating future.


The country withdraws the commonly existing "trash" in small steps and wants to change it into ecological ones, which are often filled with biomass. What is this biomass you will learn from the following material.

Biomass is a solid or liquid substance of vegetable or animal origin that undergoes a change in the process of biodegradation. It comes from products, waste (municipal and animal) and residues from agricultural and forestry production as well as from the industry processing their products, as well as part of other waste that is biodegradable together with cereal grain that does not meet the quality requirements. Biomass is a source of renewable energy that has the greatest potential for use thanks to co-firing with coal or milk.
Classification of biomass due to origin:
biomass of wood origin - wood from forests along with by-products, eg waste from the wood industry, i.e. chips, bark;
biomass of agricultural origin - biomass from agricultural production together
with by-products and residues from the processing of green plants, fruit and gardens with by-products;
biomass from energy plantations;
biomass from municipal and industrial waste.
Classification of biomass due to the degree of processing
primary energy raw materials, i.e. wood, straw, energy crops;
secondary energy raw materials, i.e. manure, manure and other organic waste as well as sewage sludge;
processed energy raw materials, ie pellets, briquettes, biogas, bioethanol, biomethanol, esters of vegetable oils, bio-oils, biogasoline and hydrogen.
Political factors affecting the development of renewable energy sources are: National Energy Policy for 2010 - 2030 of November 10, 2009. it predicts, as shown in the table, the demand for final energy.
The state energy policy until 2030 takes into account the development and achievement of a 15% threshold of energy obtained from renewable energy sources in final energy consumption, support for producers of energy from renewable energy sources, eg through the system of certificates of origin, gradual increase in the share of biokomonets in transport fuels. Implementation of construction of agricultural biogas plants, exemption from excise energy from renewable energy sources. Achieving a 10% share of biofuels on the transport market in 2020. The growing demand for biomass is the result of the implementation of Directive 2001/77 / EC promoting electricity generated from renewable energy sources.

The use of biomass as a renewable source of energy for the production of heat and electricity is a great challenge for society and their prejudices towards unconventional energy resources. The mobilization of citizens through the use of renewable energy subsidies is a very important step to overcome stereotypical thinking regarding the use of biomass as a source of energy. It brings benefits to the local community and leads to increased energy security of the country, as well as to increase the number of jobs. It promotes regional development as well as protects the natural environment by reducing the accumulation of harmful chemical substances into the atmosphere.
Exploitation of biomass for energy needs still requires its dissemination and promotion.

Poland's sources of biomass used as solid fuel are:

wood from forests, wood industry;
straw, waste in agricultural production;
energy plantations, e.g. willow, oil plants, etc .;
organic waste.
For industrial use, wood from forests and the wood industry and agricultural residues is used. Local biomass from forest commas, waste from green areas and sewage sludge is used for local use. Biomass from deliberate crops, whose planting scale is small, have the greatest potential. Currently, the basic component of biomass as an energy carrier is wood and its waste, which is of great importance especially for industry.

Demand for biomass is reported by:

power plants;
heating plants;
individual clients.
Diversification of energy sources will allow to increase energy security and independent economic growth from the level of non-renewable energy resources use. Regardless of the situation on international fuel markets, renewable energy sources will always be available because their occurrence is natural and the amount depends only on regional conditions. The production of energy from renewable sources leads to economic recovery through the acquisition of renewable raw materials, construction of appropriate installations and distribution of these devices, which leads to the creation of new jobs. The use of modern and environmentally friendly technologies promotes environmental protection and very often leads to the development of tourism and agritourism. From an economic point of view, it reduces the costs of energy and heat generation. Renewable energy sources are becoming an alternative to conventional energy sources due to the constantly rising prices of fossil raw materials and the state of the natural environment. Unconventional energy sources by nature have a local character and thanks to this installations using these raw materials avoid the problem of heat transfer over long distances. An additional economic benefit is the change in the direction of cash flow for coal, oil, and natural gas, which leads to the riches of other communities. The use of local renewable sources leads to partial cash in the region, feeding the local economy while leading to its dynamic development. Energy obtained from renewable sources allows to reduce emissions of these pollutants, which include: CO2, SO2.
The reduction of non-renewable fuels combustion has an impact on:

reducing air pollution;
reduction of soil and water contamination;
improving the living conditions of plants and animals;
food quality.
Advantages of biomass
the possibilities of using cohesion funds and structural funds for the reduction of carbon dioxide;
increasing the country's energy security thanks to the development of biomass consumption;
wide range of applications;
low costs of generating energy from biomass;
development of technologies reducing the emission of harmful chemical compounds;
growing interest in the use of biomass;
high biomass potential.
Disadvantages of biomass
relatively low calorific value of biomass in comparison to fossil fuels;
the lack of a developed biomass market;
a big threat from natural gas-based energy;
unstable energy policy.
