Biosolution for efficient energy production
Sustainable growth requires an increased use of renewable energy sources. The usage of CO2 neutral combustibles contributes to combating climate change and also provides wide-ranging financial benefits. Vapor boiler plant series is designed to provide long-term, energy efficient and ecological solutions. With our boilers, the final user can concentrate on the production of clean energy. Vapor relies on leading edge know-how, and our plants are manufactured in Finland in the company’s own facility, which has fifty years of experience in boiler and pressure vessel manufacturing. Our leading principle is to fulfil our promises and offer our customer the most advanced solutions at the market. The Vapor bioboiler plants of the efficiency range of 0,5-10 MW are excellent solutions for steam and heat production. Vapor boiler plants are based on a patented grate solution. We offer comprehensive solutions, including design, manufacture, installation, commissioning and maintenance as required by the customer, covering the whole boiler plant process:
– Fuel reception and handling
– Fuel feeding equipment
– Combustion air and flue gas equipment
– District heating/steam system
– Boiler and convection unit
– Ash discharge equipment
– Flue gas treatment
– Electrification, instrumentation and automation
– Reserve power machine
– Boiler house construction including HVAC equipment
– Erection, commissioning and training
The Vapor boiler plant process has been carefully designed and measured.
The plants are highly automated, and thanks to this, the process
is easy-to-use, highly controlled and safe. Our cooperation network
comprises the leading component and system suppliers of the energy
industry. Hence Vapor’s plant deliveries incorporate the leading knowhow
of the sector, also as regards auxiliary devices.
ADVANCED PLANT TECHNOLOGY
Suitable fuels for Vapor bioboiler plants include woodchips, sod peat, wood and peat pellets, briquettes, bark and sawdust. The fuel is typically received and stored in a push feeder storage, from which conveyors move it to the feeding bin through screening and the crusher, if necessary. From
the feeding bin, feeding screws take the fuel into a mechanical grate. An extremely high efficiency of combustion is achieved by well controlled air injection. Primary air is divided by means of multiple sections below the grate. The fuel bed burns evenly in the mechanical grate, as the movement of the grate can be adjusted to the required load range. Thanks to these features, combustion in the grate is efficient and the share of unburned fuel very low. Vapor’s grate combustion is a reliable and functional technology.
QUALITY SOLUTIONS FOR ALL OUTPUT RANGES
In the output range of 0.5-3.5 MW, bioboiler plants are built with an integrated diagonal grate in the combustion chamber of the pressure vessel. This compact structure usually yields an efficiency exceeding 90 %. The round pressure vessel can be fitted to the pressure range of 6-16 bars, and the structure also enables the production of steam. In the output range of 3.5-10 MW, the bioboiler plants utilize water tube
boiler construction, where the grate is located in a water tube furnace. After the water tube boiler, the flue gases go through a flue gas convection unit. This solution enables the usage of high pressures. Both of these constructions have a low emission level, thanks to the efficient
combustion and controlled air injection. The humidity of the combustible can vary between 8 and 55 %. The usability of Vapor plants is even higher than 95 %. Due to the large tubes the boilers do not soot easily, and the soot blowing is easy to do. The process does not have to be interrupted during the soot blowing. The high industrial standard of the components leads to a long service life, and the need for maintenance is low. The boilers have been designed for a service life of 25 years. All plants are designed to be controlled periodically, and all our plants come with a remote control option. Vapor bioboiler plants are delivered as removable block-constructed factory modules or, alternatively, the plant can be constructed on site. Vapor plants are supplied as turnkey deliveries, enabling the customer to concentrate on energy generation with leading technology.
