Climate-friendly heating with biomass

Thanks for the article too regenerative heat through bioenergy by Thomas Handrich von Alternative house technology.

As energy demand continues to rise, fossil energy sources such as coal, natural gas and oil are becoming scarcer. In addition, fossil fuels are considered to be one of the causes of global warming.

In order to be able to guarantee an affordable energy supply in the future, we have to refrain from fossil energy and instead rely on renewable energy such as solar and wind energy, hydropower or biomass. Anyone who thinks today can not only save money in the future, but also make a valuable contribution to climate protection.

Wood chips for heating

Biomass heating technology on the advance

In recent years, the share of renewable energies in total heat consumption in Germany has risen continuously, like one Statistics of the Federal Association for Renewable Energies disclosed. The future forecast of the industry is also positive: By 2020, the share of renewable energies in heat consumption should be 25,1 percent.

Biomass heating technology, which is a cheap and climate-friendly way of generating heat, has a significant market share. If you want to heat with renewable fuels, you will find a wide range at specialized distributors of heating technology based on renewable energies Range of biomass heaters for private households.

In terms of energy technology, the term biomass includes both animal and plant products that are used to generate heating and electrical energy and as fuel.

As a rule, easily metered pellets, wood chips or press cakes made from compressed plants, wood or biological residues are used to fire biomass heaters. The advantage of these fuels is, on the one hand, their unlimited availability and, on the other hand, their CO²-neutral energy generation, since their combustion only releases as much CO² as was previously absorbed organically.

The purchase of a biomass heating system is associated with an initial investment, but ensures significant cost savings in the long term. Renewable fuels cost significantly less than, for example, gas or oil, which will become even more expensive in the future due to their increasing scarcity. In addition, the state subsidizes the installation of biomass plants to promote the switch to renewable energies in private households as well. On the Internet you can find out about the State funding for solid biomass combustion plants inform.

Wood pellets for renewable heat

Advantages of biomass heating

Biomass heating is easy to use. When properly installed, the system works fully automatically and is also very easy to maintain. Pellet heaters have a particularly long operating time and the burn time of a filling can be up to 100 hours, depending on the model and heat requirements. In addition, modern biomass heating technology enables the efficient use of fuel by electronically monitoring the combustion process. In this way, energy losses can be avoided and unnecessary costs can be saved.

And since mineralized ash, which is created by burning biomass, is also a natural product, it can also be used as a fertilizer for plants in the garden. This closes the ecological cycle again and saves disposal.

  1. And that comes from the chimney:
    Ideally, only wood dioxide, ash and water are produced when wood pellets are burned. This carbon dioxide does not contribute to global warming if only as much wood is burned as it grows - because then renewable trees and shrubs bind the carbon dioxide created during the combustion. In practice, wood always contains small amounts of nitrogen, sulfur and chlorine compounds. This creates harmful nitrogen and sulfur oxides and hydrochloric acid during combustion. In addition, dust gets into the air, more than 90 percent as fine dust. These very fine particles, which are not visible to the eye, can penetrate into the lungs when inhaled and thus affect health. This can result in bronchitis, an increase in asthmatic attacks or stress on the cardiovascular system. Particulate matter is also suspected of causing cancer. Incomplete combustion can also produce toxic carbon monoxide and the climate-damaging methane gas. Methane gas contributes 21 times more to global warming than the same amount of carbon dioxide. Other products of incomplete combustion are organic compounds, including carcinogenic polycyclic aromatic hydrocarbons (PAHs) in ashes and exhaust air, as well as unpleasant smelling compounds. If unauthorized fuels are used - such as wood treated with wood preservatives or varnish - even highly toxic dioxins and furans, commonly known as Seveso poisons, can arise.

  2. Hello Bernd, you are really a great friend of wood energy or combustion technology in general: D Nevertheless, many thanks for the detailed explanation of the dark side of heat generation through the combustion of renewable biomass.

    I can't really disagree with you either. In order to keep the weaknesses of the use of wood energy as low as possible, a.) A complete combustion of the wood should always be aimed for b.) The smoke should be discharged through a fireplace c.) No hazardous waste from the 20th century should be burned (dioxins , Furans). In the best case, even a wood gasifier is used (hydrothermal carbonization, pyrolysis, hydrolysis) to bring the thermal energy of wood up to date. However, this technology is not yet very socially acceptable (cost-intensive). The use of other renewable energies (solar thermal, geothermal) can also help. To avoid their weaknesses, we hope to have integrated cold fusion or tapped the energy of the ionosphere within 200 years at the latest. Then we can heat with electricity (without a guilty conscience?).

  3. I own a small coffee shop with a nice patio and I've been wanting to buy a wood pellet patio heater for those cold days. But I wasn't sure if pellet heating was environmentally friendly.. Thanks to your article, I'm convinced that I'm making the right choice.. and my plants will be happy if I use the mineralized ashes as fertilizer!
