The main purposes of a Heating, Ventilation, and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. HVAC systems had to be designed to achieve the following: Appropriate level of air filtration and the number of air exchanges. In the zones where the product could have been exposed to the environment , zones had to be controlled so that they are supplied with filtered, conditioned air. Such zones had to be so designed to achieve the ISO EN 14644-1:1999 Class 8 for particle sizes >0.5 μm in the 'At Rest' conditions.

The standard gas analyzing system consists of a sample probe, filter, sample line (umbilical), gas conditioning system, calibration gas system, and a series of gas analyzers which reflect the parameters being monitored. Typical monitored emissions include: sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen chloride, particulate matter, mercury, volatile organic compounds, and oxygen. Gas analyzing systems can also measure air flow, flue gas opacity and moisture.

Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Since smoke producing constituents are driven off during the coking of coal, coke forms a desirable fuel for stoves and furnaces in which conditions are not suitable for the complete burning of bituminous coal itself. Coke may be burned with little or no smoke under combustion conditions, while bituminous coal would produce much smoke.

Cement is a fine powder which sets after a few hours when mixed with water, and then hardens in a few days into a solid, strong material. Cement is mainly used to bind fine sand and coarse aggregates together in concrete. Cement is a hydraulic binder, i.e. it hardens when water is added. There are 27 types of common cement which can be grouped into 5 general categories and 3 strength classes: ordinary, high and very high. In addition, some special cements exist like sulphate resisting cement, low heat cement and calcium aluminate cement.

Gaseous ammonia, which comes from the plant 180 at a pressure of about 2.5 bar and temperature of about -14 ° C is liquefied in the compressors and stored in the SR-1 with liquid ammonia, which comes directly from plant 180. Nitric acid is produced by first mixing ammonia and air in a tank. In the presence of a catalyst, a reaction occurs which converts the ammonia to nitric oxide at plant 200. The nitric oxide is further reacted in the presence of water to produce 56% nitric acid.

The electrofilter removes the incombustable parts of the coal, which are carried in the fluegas stream as flyash. The fluegases stream after leaving the steam generator, coming from the air preheater, in the electrofilter through parallel, 30 cm wide openings. These gases are formed by plate-formed positively charged electrodes. Electrically isolated spray electrodes are suspended on which a negative voltage is applied. Under the influence of the electrical field the flow ash settles on he positve plate electrodes.
