Heating boilers. Part 5: Heating boilers for solid fuels, manually and automatically stoked, nominal heat output of up to 500 kW. Terminology, requirements, testing and marking

Alkalmazási terület

1.1 General This document applies to heating boilers including safety devices up to a nominal heat output of 500 kW which are designed for the burning of solid fuels only and are operated according to the instructions supplied with the boiler and misuse reasonably foreseeable by the manufacturer. This document applies also for solid fuel boilers taking the combustion air from outside the building and room sealed appliances. This document does deal with significant hazards, hazardous situations and events relevant to heating boilers used as intended and under the conditions specified in the technical documentation of the boiler (see Clause 4). The boilers may operate under natural draught or forced draught. The fuel feed may work manually or automatically. The boilers may operate in non-condensing operation or condensing operation. NOTE 1 This document does deal with boilers which are within the scope of the Machinery Directive 2006/42/EC or outside of the scope of the Machinery Directive 2006/42/EC (manual stoked natural draught boiler). NOTE 2 There is a risk of freezing condensate in the condensate drainage at low temperatures. This document contains requirements and test methods for safety, combustion performance, operating characteristics, marking and maintenance of heating boilers. It also covers all external equipment that influences the safety systems (e.g. back burning safety device, integral fuel hopper). This document covers only boilers that include burners as a unit. The document applies to the combination of a boiler body with a solid fuel burner according to EN 15270:2007 as a unit only when the whole unit is tested in accordance with this document. Heating boilers in accordance with this document are designed for central heating installations where the heat carrier is water and the maximum allowable temperature is 110 °C, and which can operate at a maximum allowable operating pressure of 6 bars. For heating boilers with a built-in or attached water heater (storage or continuous flow heater), this document only applies to those parts of the water heater which are necessarily subject to the operating conditions of the heating boiler (heating part). This document does not apply to: — heating boilers and other heating appliances which are also designed for the direct heating of the place of installation, also according to the European regulation 2015/1185/EU; — cooking appliances; — the design and construction of external fuel storage and transportation devices prior to the safety devices of the boiler; — manual stoked straw bale boilers; — CHP appliances (combined heat and power). This document specifies the necessary terminology for solid fuel heating boilers, the control and safety related requirements, the design requirements, the technical heating requirements (considering the environmental requirements) and testing, as well as the marking requirements. This document is not applicable to heating boilers which are tested before the date of its publication as an EN (European Standard). For evaluation of the requirements of this document test results of former versions of the standard may be used if applicable. NOTE 3 This document can be used as a reference for boilers > 500 kW for safety evaluation. This document does deal with all significant machine hazards, hazardous situations and events relevant to solid fuel boilers, when they are used as intended and under conditions of misuse which are reasonably foreseeable, except noise hazards. NOTE 4 The document contains requirements regarding noise but not in its full extent to cover the Essential Health and Safety Requirements (EHSR, Annex I of the Machinery Directive 2006/42/EC). 1.2 Fuels These boilers may burn either fossil fuels, biogenic fuels or other fuels such as peat, as specified for their use in the technical documentation, in accordance with the requirements of this document. Solid fuels included in this document are categorized as follows. Biogenic fuels Biomass in a natural state, in the form of: — log wood with moisture content <= M25, according to EN ISO 17225-5:2014; — chipped wood <= M35 with moisture content from M15 to M35, according to EN ISO 17225-4:2014; — chipped wood > M35 with moisture content exceeding M35, according to EN ISO 17225-4:2014; — wood pellets according to EN ISO 17225-2:2014; — wood briquettes according to EN ISO 17225-3:2014; — sawdust with moisture content <= M20; — sawdust with moisture content M20 to M50; — sawdust with moisture content <= M20 is dangerous against back burning; — non-woody biomass, such as straw, miscanthus, reeds, kernels and grains according to EN ISO 17225-6:2014. Fossil fuels — a bituminous coal; — b brown coal; — c coke; — d anthracite. Other solid fuels — Other solid fuels such as peat or processed fuels according to EN ISO 17225-1:2014.
