A battery testing system includes: a test chamber; a battery test platform within the test chamber, the battery test platform being configured to accommodate a battery and to performing a test to the battery; and an ignition device configured to combust exhaust gases produced in the test chamber during the battery test while the exhaust gasses are in the battery testing system.

The invention relates to a staggered firing for combustion of wet charge materials, consisting of the following steps: pre-combustion designed as a fluidized bed firing, heat transition in a heat exchanger, dust precipitation, and post-combustion. The staggered firing is characterized in that during the heat transition in the heat exchanger, exhaust gases from the pre-combustion are cooled and combustion air for pre-combustion is heated and then supplied to the pre-combustion.

A combustion-support-gas bypass line is provided to cause combustion support gas to bypass a preheater. A combustion-support-gas flow control damper is provided in the combustion-support-gas bypass line. An inlet temperature of a deduster is measured by a temperature sensor and the inlet temperature measured by the temperature sensor is inputted to a controller and is compared with a set temperature more than an acid dew-point preliminarily set in the controller. On the basis of a comparison result, an opening-degree control signal is outputted from the controller to the combustion-support-gas flow control damper so as to make the inlet temperature to a set temperature more than an acid dew-point.

The present invention discloses an apparatus (100), for scrubbing smoke comprising: a first tank (110), having a compartment (111), filled with a liquid; and, an inlet (112), configured to draw in the smoke into the compartment (111) from a combustion source, characterized in that, the first tank (110) includes a propeller system (113), arranged within the compartment (111) to mix the smoke with the liquid, for providing first scrubbing effect by propelling the liquid.

The present invention relates to an air purification apparatus for a coal-fired electric power plant, and more specifically to an air purification apparatus for a coal-fired electric power plant, which, first, can filter out wastes of contaminated smoke by using limewater, which, second, can filter out fine dust and carbon dioxide included in the smoke, which, third, can convert waste gas including carbon monoxide in a state in which only smoke remains into carbon dioxide by reacting oxygen with the waste gas and purify the smoke into clean air by allowing a sodium hydroxide solution to absorb the carbon dioxide, and which, fourth, can eliminate humidity from the clean air by passing the clean air through a moisture condenser a plurality of times and discharge clean air in a pure smoke state from the power plant.

The present invention relates to a process for concurrently removing CO.sub.2 and SO.sub.2 from flue gas produced by a combustion process, comprising: (a) performing a combustion process by combusting a fuel and air in a combustion apparatus, thereby creating an exhaust stream comprising CO.sub.2 and SO.sub.2; (b) compressing the exhaust stream in a first compression step, thereby producing a first compressed gas stream; (c) providing a first membrane having a feed side and a permeate side, and being selectively permeable to CO.sub.2 and SO.sub.2 over nitrogen and to CO.sub.2 and SO.sub.2 over oxygen; (d) passing at least a portion of the first compressed gas stream across the feed side; (e) withdrawing from the feed side a CO.sub.2- and SO.sub.2-depleted residue stream; (f) withdrawing from the permeate side at a lower pressure than the first compressed gas stream, a first permeate stream enriched in CO.sub.2 and SO.sub.2; (g) passing the first permeate stream to a separation process that produces a stream enriched in CO.sub.2 and a stream enriched in SO.sub.2.

Waste treatment comprises heating it in a chamber to effect pyrolysis of the waste, introducing oxygen into the chamber to effect combustion of the pyrolyzed waste, and contacting off-gas from the pyrolysis and/or combustion steps with an oxidation catalyst to convert carbon monoxide and hydrocarbons in the off-gas into carbon dioxide and water and with a reduction catalyst to convert nitrous oxides to nitrogen and oxygen. Thus, domestic waste is treated in a batch process using catalytic converters to reduce the level of toxic components before off-gas reaches the atmosphere.
