13、(EN 15034:2006) has been prepared by Technical Committee CEN/TC 57 “Central heating boilers”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2007, and
14、 conflicting national standards shall be withdrawn at the latest by May 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia,

BS EN 15034:2006EN 15034:2006 (E)4 1 Scope This European Standard applies to oi
16、l-fired heating boilers, which are declared by the manufacturer to be condensing boilers up to a nominal heat output of 1 000 kW supplied as a unit with an atomizing oil burner which meets the requirements of EN 267. NOTE This European Standard defines three classes of oil fired boilers with efficie
17、ncy requirements higher than those given for low temperature boilers in the Boiler Efficiency Directive (BED) 92/42/EEC. This European Standard completes/modifies EN 303-1, EN 303-2 and EN 304 and specifies supplementary requirements for condensing boilers. 2 Normative references The following refer

21、 definitions apply. 3.1 condensate liquid formed from combustion products during the condensation process 3.2 nominal condensing output (P) value of useful output declared by the manufacturer, in kW and corresponding to the operation of the boiler in a 50 C/30 C water temperature regime 3.3 maximum
22、allowable working temperature temperature that the material can withstand over a long period of time 3.4 condensing boiler boiler that, under normal operating conditions and at certain operating water temperatures, partially condenses the water vapour in the combustion products in order to make use
23、of the latent heat of water vapour for heating purposes and also satisfy the efficiency requirements of this European standard BS EN 15034:2006EN 15034:2006 (E)5 3.5 nominal output (PN) value of the useful output declared by the manufacturer, in kW and corresponding to the operation of the boiler in
24、 a 80 C/60 C water temperature regime 4 Requirements 4.1 Construction requirements 4.1.1 General In addition to EN 303-1:1999, clause 4.1, the following requirements shall apply. 4.1.2 Materials in contact with condensate All parts of the heating boiler likely to come into contact with condensation
25、shall be constructed of sufficiently corrosion resistant materials or materials protected by a suitable coating, in order to ensure a reasonable life for a boiler that is installed, used and maintained in accordance with the manufacturers instructions. Fuel quality requirements shall be declared by
26、the manufacturer. 4.1.3 Removal of condensation Condensation produced during boiler operation, including condensation formed in the flue and its connecting pipes, which shall be removed by means of a discharge pipe (or pipes). The internal diameter of the outside connection of the condensation disch
27、arge system shall be at least 13 mm. The disposal system, forming part of the boiler or supplied with the boiler, shall be such that: it can be easily inspected and cleaned in accordance with the manufacturers instructions; it cannot transmit combustion products into the room where the boiler is ins
28、talled; this requirement is satisfied if the disposal system incorporates a water trap; water trap has a seal of at least 25 mm at the maximum pressure in the combustion chamber at the maximum flue length specified by the manufacturer. Surfaces in contact with condensates (except purpose provided dr
29、ains, water traps and siphons) shall be designed to prevent condensation retention. 4.1.4 Control of the combustion products temperature If the combustion products circuit contains materials that are likely to be affected by heat or is intended to be connected to a flue (including seals) that is lik
30、ely to be affected by heat from the combustion products, the boiler shall incorporate a device to prevent the combustion products temperature exceeding the maximum allowable working temperature for the material as declared by the manufacturer. The device for limiting the combustion products temperat
31、ure shall be a safety temperature cut off. The safety temperature limiter shall comply with the requirements of EN 60730-2-9 for type 2 devices. The device for limiting the combustion products temperature may be omitted if the combustion products temperature in no case is higher than the allowable t
