Biomass

Biomass

The concept of alternative energy is the production of heat without the utilization of “non renewable” sources (fossil fuels). The renewable sources, such as the solid fuels are more and more present, considering the crisis of the petrol.
Biomass.
This is a word that combines a variety of solid fuels such as wood, pellet, sawdust, scraps of  wood working, etc. These fuels can be burned in heating boilers for residences. It is very convenient if this kind of fuel is locally available.
The insulated units of the ModvlvS CS series control very well the starting steps of the solid fuel boiler, improving the efficiency and the life.


Installation example

Heat source:
Solid fuel boiler.

Buffer tank loading from the boiler:
Version 1: employment of anti-condensing pump unit MCCS DN25; Δt 20 K;
Version 2: employment of anti-condensing recycling pump unit M2 FIX3 CS DN25; Δt 20 K;

Distribution:
Heating distributor HV 60/125 DN25 for 3 pump units.

Heating users:
- Low power radiator line, Δt 20 K:
unmixed pump unit M2 DN25;
- Low power radiator line, Δt 20 K:
mixed pump unit M2 MIX3 DN25;
- Low power under floor heating line, Δt 8 K:
fixed temperature pump unit M2 FIX3 DN25.
