Steam boilers with a low NOx system minimize environmental impact through dry saturated steam production. They incorporate a stainless steel economizer and natural gas burner that emit low NOx emissions. High-performance steam boilers work at 950°C gas inlet and 160°C outlet temperatures and include a gas economizer to preheat intake air. Steam boilers can produce steam from cork combustion. The CSPM-1000/12 model provides 1,000 kg/h of steam at 12 bars from cork waste, with minimal carbon generation and potential fuel savings of 215,000 liters annually.

STEAM BOILERS
What are steam boilers with a low NOx system?
Steam boilers with a low NOx system are specially designed to
minimise the environmental impact with the production of dry
saturated steam. This type of boiler incorporates a stainless steel
economiser with a cross flow integrated within the boiler and that,
consequently, allows to reach maximum efficiency.
In addition, it has a 3-way valve, 2 feed pumps, automatic purging
of sludge and salts, and a natural gas burner with low NOx emissions.
How does a high-power steam boiler work?
A high-performance steam boiler belongs to the pyrotubular variant
and works at a gas inlet temperature of 950 °C and 160°C outlet. It
also incorporates a gas economiser that preheats part of the intake
air of the gasification chamber.
Can a boiler produce steam from cork?
It is possible for a boiler to produce steam from cork. Attsu has a
steam boiler model (the CSPM-1000/12) that is specially designed
to provide 1,000 kg/h of steam at a pressure of 12 bar from the
combustion of cork and its derivatives. The same wastes coming
from the manufacturing process of this material are used to
produce the necessary heat required in this type of industry.
The resulting steam is dry and of high purity, and its objective is
the preparation, drying and sterilisation of cork stoppers. With the
use of this type of boiler, carbon generation is minimal, and fuel savings can reach 215,000 litres
in one year.

2. What is a reheated steam boiler?
The GE 1000 RV steam boiler produces high-quality steam that
overheats in the same boiler and can reach a temperature up to 310
°C. This type of boiler is mainly intended for the maintenance of
steam turbines, and its design is specially designed to withstand up
to 4,500 kg/h of steam and 20 bars of pressure.
