Waste to energy boiler process
Waste to energy (WtE) is the process of creating energy in the form of electricity and/or heat from the incineration of waste. This type of fuel has a relatively high tendency to create fouling in all parts of the boiler.

Soot cleaning systems for Waste to energy boilers
Infrasound sonic cleaning offers a cost-effective and efficient greentech solution for preventing soot accumulation in boilers, thus reducing the need for conventional soot cleaning systems that wear on heat exchangers and require lots of maintenance. Typical applications for infrasound cleaning system on waste incinerators are Economizer and SCR. For our optimization of soot blowers, HISS®, all retractable steam soot blowers are targets for optimization, saving steam or e.g. improving steam data by soot blowing more often in problematic areas, without increasing the total steam consumption of the soot blowers.
Benefits
Benefits our cleaning systems brings to the customer are:
Reduced or eliminated steam consumption for steam soot blowing. Increased production or reduced need for auxiliary boilers.
Reduced or eliminated need of shot cleaning. Reduced or eliminated operational and maintenance costs of the shot cleaning system.
Mayor vida útil de los intercambiadores de calor. Non-abrasive infrasound cleaning increases the lifetime of heat exchangers by reducing the need for conventional cleaning systems. Infrasound cleaning does not contribute to corrosion or erosion of heat exchangers. Our optimization of soot blowers reduced steam consumption and tube wear by 50 %.
Presión diferencial más baja y estable. Infrasound cleaning reaches areas that not accessible to conventional soot cleaning systems.
Fewer outages for manual cleaning. Increased availability and energy production.

El propósito de la instalación de la limpieza por infrasónidos de Heat Management era reducir, o preferiblemente eliminar, el sistema de limpieza por chorro existente, prolongando la vida útil de los tubos y manteniendo al mismo tiempo la eficacia de la limpieza.
Mälarenergi Block 6, Sweden
Prior to the installation, the customer used full steam flow in both directions when sootblowing, which is the traditional way of sootblowing. Since 90% of the soot cleaning effect happens at the first stroke from the sootblower, most of the steam on the retraction stroke is wasted and consumes expensive steam. The wasted steam can instead be used to increase electricity production.

The IPCC report from August 2021 and the results from COP26, making it clear that the energy-producing industry needs to focus even more on reaching its suitability goals. We have to look for new innovative ways not yet pursued.
SYSAV Kraftvärmeverk, Malmö Sweden
At SYSAV Kraftvärmeverk, Continuous shot cleaning was used for keeping the economizer clean as well as the convection area. The power plant had to shut down the boilers for manual cleaning of the economizer and the convection area every 10- 12 weeks.
