DS/EN 264:1991 使用液态燃料的燃烧设备的安全关闭装置.安全要求和试验

The flows of liquid fuels shall be capable of being Interrupted by means of safety shut-off devices, which, for example, are designed as automatic valves or fast closing devices. Their reliability shall be proven by type tests according to this standard. Other test methods may be allowed where necessary. 1.2 Field of application This European standard comprises safety requirements and test methods for safety shut-off devices 1n combustion plants, which on opening release, with or without delay, the flow of the fuels mentioned below and shut off without delay on clo-sing. This standard applies to the use of fuel oils. For other liquid fuels the test methods may be agreed between the manufacturer and the test institute. This standard also applies to safety shul-off devices forming part of devices having other functions, i.e. oil pumps. In this case the test methods apply To those parts or components of the device forming the safety shut-off device, i.e. those parts which are necessary for the closing function. 1.3 References CENELEC Harmonization Document 365 S2 IEC Publication 529 (1976) Classification of degrees of protection by enclosures Incorporating Amendment No. 1 (1978)

DS/EN 267:1991 整体型雾化油燃烧器.试验

This European Standard specifies the test requirements and methods for laboratory testing of atomizing oil burners of the monobloc type, with a flow rate m ≤ 100 kg/h and supplied with a fuel having a viscosity at the burner input point of (5,5 ± 0.5) mm2/s at 20 °C. These tests are normally carried out in the combustion chambers defined in paragraph 6.3. In certain special cases, however, they may be carried out in the equipment for which the burner has been specifically designed. These test methods are not applicable to burners which are part of a burner-heat exchanger combination constituting a heat generator, as 1n that case it is the whole assembly which is tested. A monobloc type burner is an assembly of components, which allows the supply and atomization of the fuel, flame supervision and adjustment of operation to take place. These component parts are either fitted together and mounted on the same equipment, or are supplied together 1n the same casing. These elements comprise, for example, a fuel pump, an atomizing device, a combustion air fan, an ignition device, a flame supervision device, a burner motor, an oil preheating device. The assembly is accordingly listed by the manufacturer.

DS/EN 230:1991 一体式燃油器．安全，控制和调节装置以及安全时间

This European Standard determines the requirements, operating conditions and test methods for safety, control and regulation devices for automatic and semiautomatic atomizing burners of the monobloc type for burning distillates and residual fuels, in the range from kerosene to. heavy fuel oils. It also applies to dual fuel burners, for use with either oil or gaseous fuels, when operating on oil. It does not however give any requirement relating to electrical safety which will be dealt with 1n the publications of other standardization bodies.

DS/ISO 1928:1980 固体矿物燃料.用弹式量热计测定总发热量并计算净热值

This International Standard specifies a method for the determination of the gross calorific value of a solid fuel at constant volume in an adiabatic, an isothermal, or a static bomb calor imeter. The result obtained by this method is the gross calorific value of the analysis sample at constant volume, the water of the combustion products being condensed to liquid at the calorimeter temperature. In practice, fuel is burned at constant (atmospheric) pressure and the water is not condensed but is removed, as vapour, with the flue gases. Under these conditions, the operative heat of combustion is the net calorific value of the fuel at constant pressure The net calorific value at constant volume may also be used, tormulae for calculating both values are given.
