gas burner

Voorbeeldzinnen

1. Gas burner with support and clamp
2. Support the gas burner on a flat horizontal surface or fix the burner to a support by means of a clamp;
3. Ignite the gas burner; the flame shall be non-luminous and approximately 4-5 cm high;
4. The gas supplied to the burner shall have a calorific value near 38 MJ/m3 (for example natural gas).
5. The ignition source is defined as a gas burner with a blue, non-luminous flame 4-5 cm in height.
6. Note the ignition results for the distance between the gas burner and the aerosol dispenser in the table provided;
7. Repeat steps (g) to (l) twice more (a total of 3) for the same can at the same distance between the gas burner and the aerosol actuator;
8. Finally the gases pass into the afterburner chamber where they are burned in the flame of a natural gas fired burner in the presence of excess air.
9. when full according to the complete procedure, with the gas burner in the range of 15-90 cm distance from the actuator of the aerosol can;
10. Repeat the test procedure for another two aerosol cans of the same product at the same distance between gas burner and aerosol actuator;
11. The auxiliary burner shall not be fed with fuels which can cause higher emissions than those resulting from the burning of gas oil as defined in Article 2(2) of Council Directive 1999/32/EC of 26 April 1999 relating to a reduction in the sulphur content of certain liquid fuels [36], liquefied gas or natural gas.
12. This burner shall be switched on automatically when the temperature of the combustion gases after the last injection of combustion air falls below the temperatures set out in paragraph 2. It shall also be used during plant start-up and shut-down operations in order to ensure that those temperatures are maintained at all times during these operations and as long as unburned waste is in the combustion chamber. The auxiliary burner shall not be fed with fuels which can cause higher emissions than those resulting from the burning of gas oil as defined in Article 2(2) of Council Directive 1999/32/EC of 26 April 1999 relating to a reduction in the sulphur content of certain liquid fuels [36], liquefied gas or natural gas.
