OverviewThe industrial boiler is a natural circulation boiler that is divided into 2 parts. The upper area is the boiler heated surface, with the lower part consisting of the grate. The end of the boiler is equipped with an economizer and air-preheating system. The boiler also features a water circulation system, flue gas system, ash system and blowing system.

To get an idea, an automatically-fed pellet boiler costs between £10,000 - £19,000, including the boiler installation cost and delivery. A smaller domestic biomass boiler starts at £5,000, and an ordinary commercial installation aimed to heat two or more buildings can cost around £20,000. Ultimately, the cost of your biomass boiler will
It is advisable to add approximately 0.3â€“0.5% by weight of slaked lime to the fuel before use in boilers with ratings up to 50 kW and 0.5â€“0.8% for boilers with ratings over 50 kW. This increases the calcium content of the fuel, thereby raising the ash fusion point and reducing the amount of clinker that can form in the first place.
Comparing the cost of biomass boilers with conventional boilers. Biomass boilers start at about £7,000 for a 12kW domestic version, which is sufficient to provide heat and hot water for a 4-bed house. A comparably sized gas boiler will only cost around £2500 to install. A bigger biomass boiler with an auto-feed hopper may cost closer to £12,000.
The following page is a guide and selection tool that enables you to pick the optimal biomass, processing method and boiler to help ease the process. We have split the task into three stages: first to understand the characteristics to look for in a given biomass, second to pick the right processing method for the ease of transportation and storage and third to pick the appropriate combustion system and pollution control â€¦

This gives a bulk weight of 650kg/m³ and produces 4.9kWh of heat per kg. We recommend only using HETAS/ Woodsure quality-assured suppliers, to get the most heat and least hassle for your money. As with wood chips, a good starting point is the Biomass Suppliers' List.
Biomass Boilers. Wood pellet fed domestic biomass boilers are available in a range of sizes depending on your heating and hot water requirements, and generally operate at 80 â€“ 90% efficiency. Biomass boilers work in a similar way to conventional gas boilers, â€¦
