    Abstract: The present invention provides environmental equipment which is able to remarkably reduce operating costs and a power generation system comprising same, comprising: a boiler; a power generation unit for generating electricity by steam generated from the boiler; first denitrifying equipment to which exhaust gas is delivered from the boiler and which sprays a reducing agent into the exhaust gas to denitrify the exhaust gas; a low-low temperature electrostatic precipitator for collecting dust of the exhaust gas provided from the first denitrifying equipment; second denitrifying equipment which sprays a reducing agent into the exhaust gas provided from the low-low temperature electrostatic precipitator to secondarily denitrify the exhaust gas and allows the exhaust gas to be provided towards a smokestack.

    Abstract: A controller for a dosing module including a pump, an inlet manifold coupled to the pump, a nozzle, an outlet manifold coupled to the nozzle, a first branch coupled to the inlet manifold and the outlet manifold and having a first flow restrictor and a first valve, a second branch coupled to the inlet manifold and the outlet manifold and having a second flow restrictor and a second valve, and a sensor coupled to the inlet manifold and the outlet manifold, includes an input/output interface and a processing circuit. The input/output interface is configured to electronically communicate with the first valve and the second valve. The processing circuit configured to selectively cause the first valve to be in a first valve first position, in which the first valve facilitates fluid communication from the inlet manifold to the outlet manifold through the first branch, and a first valve second position.

    Abstract: A vehicle exhaust system component, according to an exemplary aspect of the present disclosure includes, among other things, a housing defining an internal cavity to receive exhaust gases, at least one first catalyst received within the internal cavity, at least one filter positioned within the internal cavity downstream of the at least one first catalyst, and at least one second catalyst received within the internal cavity downstream of the at least one filter. A mixer has an inlet that receives exhaust gases exiting the at least one filter and an outlet that directs exhaust gases into the at least one second catalyst. One or more of the at least one first catalyst, the at least one second catalyst, and the at least one filter are serviceable.
