Abstract

1.1 This document is applicable to thermal cleaning systems for exhaust gas from surface treatment equipment/systems as given below in which the concentration of exhaust gas to be cleaned (for the purpose of this document, named "process gas") at the inlet to the thermal cleaning system is safely limited within the concentration ranges given in 5.2.1.2.Surface treatment equipment includes:- dryers according to EN 1539, curing equipment;- flash-off areas;- coating plants (e.g. closed spray booths, open fronted spray booths);- machines using flammable solvents for the pre-treatment and cleaning of products or equipment (e.g. barrels, tins, cans or containers);- related solvent handling equipment.This document deals only with the significant hazards from fire and explosion as listed in Clause 4, when used as intended and under the conditions foreseen by the manufacturer.The types of thermal cleaning systems covered in this document are- direct combustion, and- catalytic combustion(see definitions in 3.1.1 and 3.1.2).This document shall be used in conjunction with the relevant requirements of EN 746-1 and EN 746-2.For the purpose of this document a thermal cleaning system for process gas contains the following components: fan(s), heat exchanger, process space, main and supporting burner, injection system, power driven dampers, control and power circuits joined together for the processing of flammable substances, predominantly volatile organic compounds, by effecting oxidation.NOTE Thermal cleaning equipment is usually integrated with systems as covered by e.g. EN 1010, EN 1539, EN 12215, prEN 12921-1 or prEN 12921-3.1.2 This document is not applicable to:- thermal paint removal systems;- pyrolytic systems.1.3 This document is not applicable to thermal cleaning systems which are manufactured before the date of publication of this document by CEN.
