- Biomass that can be used to run an industrial steam boiler comes from three major sources: bioenergy crops, agricultural waste, and forestry waste. The most widely used type is forestry mulch, which comes in various sizes. - Industrial boilers are installed in ventilated boiler rooms for safety. Boiler rooms must have inlet and outlet ventilation and meet standards based on the size and fuel of the boilers. - The ATTSU CV steam manifold helps distribute steam from one or more boilers to factory lines and can isolate lines for maintenance. It includes a blowdown system and complies with European regulations.

What biomass can be used to run an industrial steam boiler?
Biomass as fuel can be found in many forms and grain sizes. These range from powders to large diameter logs. It comes from three major sources:
- Bioenergy crops
- Agricultural waste
- Forestry waste
The most widely used biomass in industrial boilers for producing steam and heat is forestry mulch, which comes in various sizes, ranging from olive stones and
nut shells to chips, shavings and bark from pruning trees.
The industrial biomass boilers that ATTSU manufactures and installs are adapted for use with any type of biomass, since it is the grille that is adapted to the
type of fuel. Thanks to the extensive experience of the professional team at ATTSU, they can provide any advice required on the energy efficiency of each type
of fuel biomass.

What ventilation systems do industrial boilers have?
When they reach a certain size, industrial steam boilers are installed in a boiler room which is necessary to ensure safety while they are operating as pressure
equipment, in accordance with local regulations.
Although the personnel responsible for operating boilers do not work there permanently, boiler rooms are places to which essential staff have access. Access
by personnel must be limited, and as such they can only be entered by authorised personnel.
Boiler rooms must be well ventilated, with a lower or upper inlet and outlet for outside air. There are pre-established criteria for the design and specifications
of ventilation in rooms containing the most powerful boilers and those using fuels such as natural gas, such as the UNE 60601 standard.

What is the ATTSU CV Steam Manifold?
The steam manifold is a very important installation in the industrial steam boiler's circuit, because it helps distribute the steam from one or more boilers to
the various lines in the factory and can divide the factory's lines for maintenance purposes.
The ATTSU CV steam manifold is designed and manufactured to order for each circuit, with the number of connections varying according to the factory's
needs. It includes an integrated blowdown system for condensates, and is certified according to the 2014/68/EU European directive.

What are recovery boilers used for?
Gas recovery or cogeneration boilers are boilers that do not produce heat as a result of combustion, but instead from the hot exhaust gases generated by
other equipment.
They are used in industrial activities that are committed to sustainability and to taking full advantage of resources.
They recover the high temperature gases emitted by another machine, turbine or engine, cool them and generate steam, improving the factory's efficiency
and its energy sustainability.
ATTSU manufactures and installs BV cogeneration boilers with maximum performance levels and savings, equipped with up to three manholes that provide
access to the circuit. They also comply with the guidelines of the 2014/68/EU European Directive.
