A particle counter includes a ventilation path, an electric-charge generator that applies the electric charge to a particle in the gas that passes through the ventilation path to obtain a charged particle, a charged-particle-collecting electrode, a heater that is capable of heating the ventilation path, and a controller for performing a particle count detection process, wherein, when the process is performed, the controller obtains a flow rate of the gas on the basis of a calorific value that is supplied to the heater and a difference between the temperature of the gas and the temperature of the surface of the heater, with the heater heating the ventilation path, and obtains the count of the particle per unit volume in the gas on the basis of the flow rate of the gas and a physical quantity that varies depending on an electric charge amount of the charged particle.

A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator includes an array of vertical wet cords stretched within a duct. The cords are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves. A plurality of these sieves are arranged to define a plurality of gaps, through which the exhaust flows. The sieves and thus the cords are space so that a vortex from a first cord affects an adjacent cord and subsequently cord. The particles are then absorbed in liquid, which can be passed through a heat exchanger filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.
