Biomass Heating Boilers and Fuel

Biomass Boilers

Wessex Eco Fuels is an appointed sales agent for the CARBOROBOT boiler, which has been specifically designed to be fed by vegetable based pellets.

Seven models ranging from 30kWh to 300kWh output performance. These biomass boilers totally replace oil and gas boilers with similar capacity.

CARBOROBOT Classic 30 "Family" (3-30kWh)

The CARBOROBOT Classic 30 "Family" is a new production. It can be perfectly employed for the heating of private houses, blocks of freehold flats, workshops, garden greenhouses, plant-houses, in fact in most buildings, where a continuous, regulated, automatic heating without control is necessary.

CARBOROBOT Classic 40 (5-40kWh)

The CARBOROBOT Classic 40 has been in production for more than 25 years. Applications as for Classic 30.

CARBOROBOT Classic 80,120,140,180 & 300 (80-300kWh respectively)

Perfectly employed for the heating of blocks of freehold flats, workshops, garden greenhouses, plant-houses, in fact in most buildings, where a continuous, regulated, automatic heating without control is necessary.

Biomass Boiler Fuel

Rape seed based pellets or straw based pellets are available from us.

Straw pellets are made from 100% natural ingredients, such as wheat and oil seed rape straw. The energy contained in the original raw material is highly concentrated, giving a fuel with very good energy qualities, calorific, with minimal amounts of ash.

Rape based pellets are 6mm wide and have a dryness rating of 91%. This makes them perfect for all hopper-fed boilers and biomass heating systems.

The burning of biomass pellets causes zero CO2 emission as the plant during its growth absorbs as much carbon dioxide, as is fed into the atmosphere during burning. The ash from burning pellets can be used as a mineral fertiliser due to its high content of elements vital for plant growth. The fuel analysis (below) of the straw pellets shows their total suitability as a heating fuel.

Straw Pellets - Fuel analysis

Currently, there are several million tonnes available to be used for energy production. This amount is subject to large fluctuations due to the conditions of crop abundance and consumption in agriculture, but generally, the tendency in this market is heading towards increasing straw supply. In connection with this, there is a surplus of straw that can be used for energy production purposes. That could help decrease damage of CO2 to the environment.

Straw pellets, as an energy fuel, contain a relatively high amount of volatile ingredients, that make this kind of fuel burn very effectively. At the same time, the content of ash and moisture remains at a constant, level.

The Characteristics of
Straw Pellet as Fuel

No	Parameter	Valuel	Unit
1	Calorific Value	18.1	MJ/kg
2	Combustion Heat	19.8	MJ/kg
3	Moisture Content	8.0	%
4	Ash Content	7.0	%
5	Pouring Density	0.54	kg/dm3
6	Specific Gravity	1.0	kg/dm3

As is shown, pellets have a high calorific value, which under proper conditions can equal the calorific value and quality of coaldust.
