Overview and types of boilers
Replace your old boiler with a new boiler conception involves a quantifiable energy savings of 25-30%. In the market there are different types, distinguished according to the principle of operation and the fuel used.
Low temperature boiler with fuel oil or gas
The low temperature boilers represent the minimum standard acceptable. They are able to modulate the power delivered by adapting to specific requests and have yield between 85 and 92%. The cost of buying a fuel oil boiler and that of a gas boiler is not very different, while the cost of running a fuel oil boiler is decidedly greater than that of a gas boiler (natural gas).
Condensing boiler oil or gas
Condensing boilers are an evolution of the preceding, being able to exploit the latent heat of condensation of the fumes and to recover it by means of a heat exchanger for reuse, continuously, in the system. The yield of this type of boilers is between 95 and 107% and this allows large energy savings compared to low temperature boilers. The fuel to recommend is methane gas since, having condensation temperature greater than that of gas oil, is much more efficient.
Wood gasification boiler
The boilers wood gasification are characterized by the fact that the individual steps of the process of combustion of the wood are phase-shifted and distinct in time. The perfect combustion of the material is ensured by the presence of specific probes that monitor the oxygen content of the fumes. The new boilers strips and blocks of wood are able to modulate their performance depending on the internal loads, which can reach values up to 50% of nominal yields. E 'should these boilers are equipped with an accumulator that stores the heat and allows it later reuse.
Boiler wood chips
The boilers to wood chips are very suitable for heating large spaces (residential complexes, hotels ...) and the level of BIOCOMFORT that are able to offer is far superior compared to that of a diesel boiler. Differently from the previous ones, the power system is not automated manual but as is the ignition. As in wood gasification boilers, boilers for wood chips are equipped with a probe for the control and optimization of the combustion process.
Pellet plants
The automatic pellets can be used for heating of individual units or to feed the central heating system of larger complexes. They have large managerial advantages such as the automatic adjustment of the performance, the ignition, the cleaning of the heat exchanger and the discharge of the ashes automatic. And 'calculated that one kilogram of combustible material has a calorific value equivalent to 0.5 liters of fuel oil and that for every kW of thermal power takes about 0.9 cubic meters for the storage of the material.
