A flue gas treatment device (1) is provided. A wet electrostatic precipitator (11) and a flue gas heater (13) are integrated in an integrated flue housing (14) of the flue gas treatment device (1), thus the occupied area of the flue gas treatment device (1) is smaller than that of the solution with devices being arranged separately. Furthermore, since a bidirectional transition flue is not required to be arranged in the integrated flue housing (14), the flue gas has a good flow uniformity, and further it is not required to arrange a flow equalization orifice plate in the flue, thus the flue gas has a small resistance, thereby reducing the power consumption of the draught fan and increasing the efficiency of the power plant.

Method and device for operating a conveyor for a combustion product, in which, during the conveyance, through the detection and analysis of properties (such as volume flow, mass flow, moisture, temperature, grain size) of the combustion product by means of microwaves, a control of transport parameters (such as transport speed, cooling of the combustion product, supply of combustion product, degree of crushing) is realized. It is herein possible to protect the conveyor thermally and mechanically and, at the same time, to ensure real-time regulation of the composition and quantity of the combustion product for following treatment steps.

A sootblower having a nozzle that includes one or more deep reaching jets aligned with its respective platen bank to clean slag deposits inset from the leading edge of the platen bank. The nozzle also includes one or more edge cleaning jets substantially angled with respect to the platen bank for cleaning the leading edges of the platen bank. For most applications, the major axis of the sootblower is perpendicular to the major axis of its respective platen bank, resulting in a sootblower with a nozzle having angled and perpendicular jets, referred to as angled-perpendicular nozzles. The jet sizes are selected to balance the opposing components of force perpendicular to the sootblower to avoid the imposition of torque on the lance.

A nozzle for the spraying of black liquor in a recovery boiler has discharge orifice inserts that can be removed and replaced with other inserts, to provide variable spray patterns, by changing the size and/or shape of the orifice of the nozzle, without requiring replacement of the entire nozzle body, to enable fine tuning of the atomization of the spray. Adjustment of the orifice height provides adjustment of the atomization and the spray angle of the discharge.

A modular design for large pulse jet fabric filters (PJFF) is divided into similar compartments, which are each shop-fabricated in quarter sections prior to delivery to the power plant site. The quarter sections of the compartments are modular and sized so that they can be fabricated at a shop located away from the power plant site and transported by truck over public roads to the power plant site. Once delivered to the site, the quarter sections are bolted together and seal welded to form a PJFF compartment, without requiring additional internal fabrication or welding. The assembled compartment is then lifted onto the support structure as an assembled unit and bolted and/or welded in place. The additional components of the PJFF may also be shop-fabricated offsite to further the benefits of the modular design.

Methods and systems for reducing emissions produced in a combustion system are described. A sorbent material is introduced into the emission gases flowing from the combustion system. Sound waves are also applied to the emission gases in the flow path. The sound waves can be introduced into the emission gas flow path at a location upstream from where the sorbent is introduced into the emission gas flow path. The sound waves can also be introduced into the emission gas flow path such that the sound waves travel in a downstream direction in the flow path. The emissions can include Hg and acid gases such as SO_(2). The sorbent material can be trona or activated carbon. The sound waves enhance mixing of and mass transfer between the sorbent and pollutants in the gas thereby reducing the amount of sorbent necessary to reduce harmful emissions.

A variable flow device that can be used to dewater an ash slurry is described. The variable flow device includes a pipe section having a plurality of adjustable openings in the sidewall. The variable flow device can be can be attached to a slurry discharge pipe and positioned above the horizontal section of a submerged scraper conveyor (SSC) located remotely from a boiler or furnace where bottom ash is generated. A bottom ash dewatering system is also described which includes an SSC having an overflow trough system. The trough system includes trough sections adjacent each of the sides of the SSC and one or more trough connecting sections. The SSC equipped with the variable flow device and/or trough system can receive a high volume wet ash slurry discharge while minimizing particulates overflowing into the overflow trough system.

Techniques relate to a cleaning device for an interior of a thermal power plant carrying flue gases, especially a so-called soot blower. The cleaning device includes at least one rigid lance having a base and a lance add-on part which includes at least one nozzle, the lance add-on part being detachably connected to the base. At least the lance add-on part includes at least one sensor for measuring an environment parameter. The techniques further relate to a method for installing such a cleaning device and to a cleaning and monitoring method for defined areas of the interior of the thermal power plant.
