Biomass Incinerators

Biomass Incinerator

Biomass Fired
Our Biomass Incinerators utilises biomass fuels as available to bring the incinerator up to temperature and as an auxiliary fuel. This replaces diesel or gas for sites that are remote or don’t have a readily available supply of fuel.

Easy Installation
With no diesel or gas supply infrastructure needed, installation is a lot easier and faster, making it ideal for quick deployments during emergencies or for remote mines or military camps. 

Certification
Macrotec is certified to the following standards:

ISO 9001:2015 | Quality Management Systems
ISO 14001:2015 | Environmental Management Systems
ISO 45001:2018 | Occupational Health & Safety Management 

Design

Our Biomass Incinerators are very similar to our standard incinerators, with two chambers, combustion air fans, and a stack.

Biomass Incinerator

Incinerator
All our incinerator models have two chambers, with a large hearth to help distribute the waste, and a large secondary chamber to promote settling of particulate matter (dust). The chambers are also sized for a two second reaction (retention) time.

We use a high temperature alumina-silicate refractory, with a cold crushing strength of 80Mpa and service temperature of 1,500˚C to cast our incinerators. The refractory is acid resistant with very high abrasion resistance. We also insert 100mm of low-density insulation, giving an incubator a typical R-value of 1.54m²K/W, minimising heat loss for lower fuel consumption and a safer working environment.

All our incinerators operate on a continuous feed basis. This entails waste being loaded on fixed intervals with ash being removed from the rear without the need to stop. Due to not stop and starting as you would with a batch incinerator, biomass fuel consumption is improved (no preheat required), and emissions are also improved due to a more controlled combustion process.

Stack
The standard stack height on our incinerators ranges from 7m to 15m, depending on the model size, with taller stacks optional. Our stacks are taller than most of our competitors for good reason, the increased hight increases the draft, increasing the velocity of the flue gas releasing it at greater height resulting in better dispersion.

According to EPA (Environmental Protection Agency – USA), Good Engineering Practice for stacks is calculated as H + 1.5L, where H is the height of the building itself or any significant nearby structure or structures and L is the lesser of the projected height or width of the building in question. If this is applied to the typical building in are mote setting, away from larger building, a minimum stack height of 7m would be recommended. This needs to be calculated on a site-by-site basis and might require a taller stack.
