First of all, a technical clarification is necessary in the wider sense, motor fuels are chemical compounds, liquid or gas, which are burned in the presence of air to enable thermal engines to run gasoline, diesel fuel, jet fuels. The term heating fuel is reserved for the production of heat energy in boilers, furnaces, power plants, etc. 

Potential applications for CA-CDI technology include the purification of boiler water for fossil and nuclear power plants, volume reduction of liquid radioactive waste, treatment of agricultural wastewater containing pesticides and other toxic compounds, creation of ultrapure water for semiconductor processing, treatment of wastewater from electroplating operations, desalination of seawater, and removal of salt from water for agricultural irrigation. 

The Cello pulse combustion burner system is an ex sitn technology for the enhancement of combustion devices. Cello pulse combustion can be incorporated into the constrnction of most new combustion devices or can be retrofit to most existing incinerators, boilers, and dryers. The system can be used to treat any material typically treated in a conventional incinerator, including soils, sludges, medical wastes, and liquids contaminated with volatile organic compounds (VOCs) or semivolatile organic componnds (SVOCs). The CeUo system has been installed in commercial systems and is commercially available. 

Flue-gas from boilers fired with liquid or solid fuels contains fly-ash and gaseous contaminants such as CO, NOx, SO2, or volatile organic compounds (VOCs). Emission regulations require their removal, which is achieved by a sequence of after-treatment processes. The after-treatment usually comprises a filter to remove solid particulates operated at approximately 150 °C, a wet scrubber for the removal of SO2 with an alkaline solution operated at approximately 50 °C, and finally a selective catalytic reduction (SCR) unit, which converts NOx to N2 with the help of NH3 at approximately 370 °C (Fig. 15.1) [4]. During this process, the flue gas is cooled down and then heated up again, which requires additional heat transfer equipment, with its inherent energy losses.

On cooling the gas phase some gas components condense and thus lead to the formation of deposits in the boiler. Table 7.9 shows the composition of the condensed phases and the residual waste gas. The change in concentration of the main gas components is low on rapid cooling from 1600 to 700 °C. The condensed phases mainly consist of compounds of K and Na with Cl, P, and S. The low-melting sulfates, phosphates, and chlorides form first a liquid layer where solid dust particles can be deposited by sticking. The composition of the input fuel (coal, and waste material) besides the temperature and O2 partial pressure in the combustion chamber, determine... 

Another major use of tetrachloroethylene is as a vapor and liquid degreasing agent. Since tetrachloroethylene dissolves many organic compounds, select inorganic compounds, and high-melting pitehes and waxes, it can be used to clean and dry contaminated metal parts and other fabricated materials. It is also used to remove soot from industrial boilers (Verschueren 1983). Tetrachloroethylene has been used as an anthelmintic in the treatment of hookworm and some nematode infestations, but it has been replaced by drugs that are less toxic and easier to administer (Budavari 1989 HSDB 1996). 

Coal tar is black or dark brown-colored liquid or a high-viscosity semisolid that is one of the byproducts formed when coal is carbonized (Chapter 16). Coal tars are complex and variable mixtures of polycyclic aromatic hydrocarbons (PAHs), phenols, and heterocyclic compounds. Because of its flammable composition coal, tar is often used for fire boilers, in order to create heat. Before any heavy oil flows easily, they must be heated. 

Vapor-phase inhibitors are added as gases or volatilize from a hquid inhibitor. In boilers, volatile basic compounds such as morphohne or ethylenediamine are transported with steam to prevent corrosion in the condenser tubes by neutralizing acidic carbon dioxide. In gas lines, the volatile inhibitor is present in the gas phase, separate from any liquid in the line. Compounds of this type inhibit corrosion by making the environment alkaline.
