Feb. 1, 2018 - Canadian Biomass takes a look at the newest boiler technology for Canadian customers in 2018.
ProcessBarron has developed proprietary techniques using computational fluid dynamics (CFD) analysis to “particle-track” the heavier, wear-agent particles in the gas stream. Particles greater than 15 microns are the ones that create the erosion. Using CFD, rotor geometry is augmented or altered to control the path of these heavy particles through the rotor. By minimizing their contact in highly stressed areas of the rotor to eliminate the erosion, a substantial increase in rotor life is possible.
Produits Forestier de Petit Paris, a 7.5 MW (25.6 MBTU) boiler installation was the company’s third project using steam energy. Installed in 2016 it was designed to produce five to 16 t/h steam for the dry kiln of the sawmill. It’s the first biomass boiler, which can provide an efficiency superior to 90 per cent using bark with high humidity (greater than 65 per cent). The boiler room consists of a 7.5 MW (25.6 MBTU) boiler that is fed with an automatic moving floor and independent conveyor equipment.
Turn waste into power with Outotec’s robust waste to energy technology. Outotec’s proven solutions generate valuable energy from variable wastes, ranging from municipal sources such as SRF, RDF, construction and demolition waste, to commercial and industrial wastes and a wide variety of agricultural wastes. The technology works even with difficult fuels, such as those with a high moisture or ash content, and offers the possibility to use fuels over a large range of calorific values, from eight to 30 MJ/kg. Outotec’s technology boasts minimal emissions and low carbon in ash, with over 99 per cent carbon burn-out, and ensures compliance according to local regulations. The system eliminates bottom ash, with only clean, ready-to-recycle, non-combustible material from fluidized bed.

Precision Energy Services
Precision Energy Services (PES) biomass boilers and energy systems convert a plant’s waste into energy. In 2017, PES commissioned the second paper mill sludge-to-energy system for Atlantic Packaging in Toronto. The PES’ fluidized bed boiler system produces 35,000 PPH of steam and hot gas gases to dry 100,000 tons per year of sludge, offsetting natural gas consumption and tipping fees paid for sludge disposal, resulting in a three-year payback. PES supplied the sludge handling system, fluidized bed combustion, boiler system, ash system and gas cleaning system.
Messersmith systems allow a 10:1 turn down ratio. Fuel is moved onto the specially designed grates in the combustor to be burned. The system can burn biomass fuels such as wood chips, sawdust, whole tree chips or other clean biomass with moisture contents from three per cent to 50 plus per cent. High combustion temperatures and PLC control of combustion air results in clean, efficient combustion with low emissions and only a small amount of ash. Messersmith Biomass Boiler Systems are able to deliver hot water, as well as low or high pressure steam, as well as power generation.
Krann biomass boiler uses a low-emission gasifier/furnace as its heat source. The furnace has a stationary grate with no moving parts. It produces very low particulate emissions, typically with no flue gas cleaning equipment. The flyash accumulation on boiler heat transfer surfaces is greatly reduced thus minimizing equipment cleaning and shutdowns. The system ranges from 1 MW to 15 MW of heat output and can be used for boilers (steam, water, hot oil), drying, CHP, etc., as a cost-effective alternative to traditional wood burners. It can handle a wide range of moisture and ash content fuels. The heating system includes fuel storage, gasifier/furnace, boiler, ash discharge and exhaust and is fully automated.
Woodco Energy, the Irish manufacturer of biomass boilers, recently launched its Prestige range of pellet boilers in the Canadian market. The boilers underwent UL/CSA accreditation in 2017 and are fully approved for sale in Canada. The prestige is available in 25 kW and 37 kW models. Uniquely the Prestige range can use thermal oil as a heat medium (instead of water) thereby allowing it to be the used with its new co-gen (microCHP) unit. The co-gen can provide up to 10 per cent electricity, so the 25 kW Prestige can provide 2.5 kW electrical power via the co-gen unit. The prestige is also available in a 37 kW model. The company has enquiries from Yukon, N.W.T. and Ontario for Woodco’s co-gen units and CSA approval is likely to be obtained this spring. Cogen will available for sale in Canada immediately thereafter.
