Briquettes for heating

fuels such as wood and coal, more confident replacing heating briquettes for the production of which use waste from the food, light industry and wood processing industry.And from an economic and from an environmental point of view, pressed briquettes is much more profitable, because at a very affordable price, they have a very high energy efficiency and low carbon dioxide release.Depending on the type of waste pellets are wood, coal, peat and pressed from sunflower husks.

Each speciesbriquettes has its own characteristics and advantages.And although they are perfectly suited for heating in a domestic environment, it's worth more familiar with their characteristics, to select the best option.

Forms of fuel briquettes

Wood briquets

This type of briquettes obtained by compression of various wood waste - dead wood, sawdust, shavings, wood substandard.Before compressing the waste is heated to a certain temperature, whereby the cells released from the adhesive - lignin.Because of lignin pellets acquire high strength and retain their shape during transport and storage.

advantages of solid wood briquettes to be apparent:

  • briquettes density is constant and amounts to 1240 kg / m³, wood density depends on the species and ranges from 150 to 1280 kg / m³;
  • maximum 10% humidity briquettes, wood - from 20 to 60%;
  • by combustion ash briquette volume equal to 1% of the total weight of the tree - 5%;
  • by burning briquette allocates 4,400 kcal / kg, wood - 2930 kcal / kg.

In addition, there have wood briquettes and other advantages:

  • densified wood during combustion does not spark and allocates very little smoke;
  • boiler temperature is kept constant;
  • burning time of briquettes 4:00;
  • remaining after burning coals are perfect for cooking over an open fire;
  • correct form of briquettes makes them easier to transport and storage.

sale is no fuel in cubic meters, like a tree, and in kilograms, which is much more profitable.

Coal briquettes

coal briquettes

Coal briquettes

This type of briquettes is obtained from coal screenings.First sifting comminuted, mixed with a binder, and then compacted under high pressure.

Main properties of such fuel:

  • coal briquettes do not smoke;
  • not emit carbon monoxide;
  • time of combustion in conventional boilers from 5 to 7 hours, an adjustable air supply - 10 hours;
  • suitable for use in a domestic environment;
  • have a compact form;
  • combustion of which gives 5200k / cal and maintain a constant temperature;
  • maximum amount of ash - 28%;
  • have a long shelf life.

Coal briquettes are the most optimal fuel in the harsh winter, when because of the low temperature pressure drops in household gas systems.Briquettes burn at any temperature, as long as there was a constant flow of air.

Peat bricks

Peat bricks

Peat bricks

To produce peat briquettes are dried, heated and compressed under high pressure.The result is a neat lightweight bricks dark color.When regulated air supply of peat briquettes maintain temperature for 10 hours, making it easy to heat your home during the night.

Basic properties:

  • suitable for all types of stoves;
  • heat is 5500-5700 kcal / kg;
  • volume of ash 1% of the total volume of the briquette;
  • affordable price;
  • minimum amount of impurities in the composition.

ash that remains after the combustion of the fuel can be used as an effective lime and phosphate fertilizer.For many owners of private farms, this is a decisive factor in the choice of heating briquettes.Since peat refers to flammable substances, it should be kept at a safe distance from open flames and heaters.Even waking up from its packaging dust can ignite and cause a fire, so you need to handle the briquettes properly.

husk briquettes

Briquettes are made ​​from the husks

husk briquettes

the husks of sunflower, buckwheat hulls and rice, rye waste, oats and even straw, widely used for the manufacture of fuel briquettes.The most common are briquettes made of sunflower husk, as in the production of oil remains high percentage of waste.Maximum humidity husk compression is 8%, which increases the heat output and shortens the time of ignition.

  • briquettes density is 1.2 t / m³;
  • heat - 5200 kcal / kg;
  • ash volume from 2.7 to 4.5%.

Additional benefits:

  • absence of harmful impurities;
  • affordable price;
  • long burning time;
  • easy storage and transportation.

to lay less fuel should be purchased coal or peat briquettes;if you want to ash for fertilizer, the best choice will be wood briquettes from husk.They are the most affordable.And in order to correctly identify, it is recommended to buy a small package for each type.This will help to accurately assess the strength of the briquettes, the duration of the combustion, the amount of heat and make the best choice.
