Generators of Hot Gases the Burning of Biomass
The combustion (burning) of solid biomass in systems called furnaces or burners, comprising the combustion chamber, grate, air vents, feeder and ashtray.
Your goal is to convert the chemical energy of fuel into thermal energy, thereby generating the hot gases that can be used in dryers, heaters, thermal fluid, ovens, incinerators, boilers and in other applications both for industrial use as domestic.
Gasification of biomass
The burners of biomass Lippel are also suitable for the process of gasification of biomass, process, old-fashioned, but that currently has a renewed interest mainly because of cleaning, and versatility of fuel generated (gas), when compared to solid fuels.
Cleaning refers to the removal of chemical components harmful to the environment and to human health, among which is sulfur. Versatility refers to the possibility of alternative uses, such as in internal combustion engines and gas turbines.
An example is the generation of electricity in isolated communities of networks of electrical energy, through the burning direct the gas in internal combustion engines.
Another advantage of gasification is that, under suitable conditions, produces gas synthetic, that can be used in the synthesis of any naturally occurring hydrocarbon.
These firing systems are designed according to the type and quality of solid biomass available. The functions of the combustion system include:
- Mix the air and fuel;
- Evaporate the moisture of the fuel;
- Raise the temperature of the fuel;
- Provide a complete combustion;
- Create turbulence for mixing the gases of combustion;
- Conserve a continuous burning of the fuel.
The burners of biomass have emerged also as an alternative to the use of renewable energy in place of fossil fuels. This need for large energy demand for thermal-electric generation combined with the low cost of the dual fuel burners solid made with us to develop a series of equipment suitable for an efficient combustion of various types of biomass.
For the burning with the flow against the current, and the fuels used can be humid, ranging around 25 to 50% and the ash content can be greater than 1 %. To supply with screw, fuels formed particle size (around 5 cm) and homogeneous should be used, as for example, wood chips, and sawdust.
Fuel, powdered, irregular (slivers up to 35 cm in length), and hydraulic systems-power fuels are applied. These are applied to a range of fuels, such as, chips, irregular, and mixtures with other fuels, bark, trimmings trees, recycled wood, among others.
In the burn-in cross-flow, fuels such as pellets, briquettes, others, sawdust, wood chips with up to 25% moisture can be used and the ash content can be greater than 1%.
