AGRICULTURAL INDUSTRY

Our eco-friendly biomass heating technology provides room for sustainable agricultural practices and optimised production processes. 

We can specify, supply, install and maintain bespoke biomass heating solution for multiple agricultural and agri-processing applications. Typical agricultural heating solutions include, but are not limited to, Poultry houses, Dairies, Greenhouses, Drying processes and more.

Poultry Farm Case Study

Heating plays a crucial role in the chicken industry, and is recognised as one of the key performance factors influencing production data like feed conversion – and mortality rates. Heating also constitutes a big portion of production input costs in chicken farming. Heat is usually derived from fossil fuels like coal or gas, combusted in burners, to provide the required heat energy to heat broiler houses and hatcheries.

Biomass in the form of wood chips or wood pellets could act as economical and environmentally sustainable alternative to these traditional fossil fuel.

Please see below poultry farm case study, highlighting the economic and environmental saving achieved in changing a client’s broiler heat load from coal to biomass.

BACKGROUND

The brief was to change the current broiler heat load from coal to biomass with economically viable and environmentally sustainable fuel and technology. After the initial feasibility based on existing historic data proved favourable a full proposal was presented.

PROJECT HIGHLIGHTS AND RESULTS

Overall OPEX savingsIn a straight-line cost comparison – biomass offered a 42% saving compared to the client’s current coal usage and associated operational and maintenance costs.
Substantial emission reductionA switch to biomass had a substantial emission reduction in harmful gasses like SO2 and NOx. It also had lower particulate matter emissions than coal with almost no visible smoke (CO) from the burner stack.
Better heating performance related to an increase in productionBetter temperature modulation by the biomass burner related to a better Feed Conversion Rate, lower mortalities and ultimately more broiler weight. In other words, more kilograms of chicken were produced, with less mortalities and input cost, due to better temperature regulation.
Toxic ash reductionThe average ash content of wood chips is 1.6% versus the 18 to 24% of lignite coal. Furthermore, coal ash contains high levels of sulphur and heavy metals, and is regarded as toxic, requiring certified disposal. Whereas wood ash is environment friendly, and a sough after soil ameliorant used in agriculture.
Electricity savingIn this project considerable electricity saving were achieved due to the operational changes directly related to the fuel substitution.
Near Zero Carbon TaxIn this project a 98% reduction in carbon tax were achieved.
Competitive edgeSavings in heating and associated costs and the resulting increase in production could contribute to a competitive business edge.

Our technology

A typical biomass solution for projects of this nature includes a central heating system consisting out of the following sub-systems:

  • Biomass Boiler with flue system
  • Fuel Storage
  • Fuel transport system
  • Air distribution ducting
  • Management modules and controls with internet connection

Central & district heating applications

Central Heating refers to a process of heat transfer either using a fluid or air as heat transport from one location to the next via pipes radiators or vents.

District heating, also known as heat networks or tele-heating refers to larger scale systems for distributing heat generated in a large centralized location through a transport system for residential and commercial heating requirements.

At CALORE we specialize in central and district heating project conceptualization, design, implementation, commissioning and maintenance.
