[接上页] (c) in the case where it is to be expressed in Degrees Engler, the test procedure laid down under BS 434: 1984 of the British Standards Institution. (L.N. 262 of 1987) Cap 311B Sched 2 METHOD OF TAKING SAMPLE OF DUST AND GRIT [regulation 6(2)(a)] 1. Any sample required to determine the grit or dust burden from any furnace, oven, chimney, flue or industrial plant shall be taken when the appliance or plant is operating under normal running conditions and the period during which the sample is taken may include any period when customary peak loads are experienced. 2. Not less than 8 increments comprising a sample are to be taken from points uniformly distributed across the section of the chimney or flue. 3. The sample is to be taken in accordance with the isokinetic principle. 4. The sample is to be collected in compliance with Reference Methods 5 of the United States of America Environmental Protection Agency for determination of particulate emission from stationary sources. (L.N. 262 of 1987) 5. When 8 or more increments are taken from sampling points at any one cross section of the chimney or flue, the combined increments are to be placed together in one container. (L.N. 262 of 1987) Cap 311B Sched 3 METHOD OF TAKING SAMPLES OF DUST AND GRIT FOR SIZE ANALYSIS OR DETERMINATION OF THE RELATIVE PROPORTION OF DUST AND GRIT BURDEN [regulation 6(2)(b)] 1. Any sample required for size analysis or determination of the relative proportion of dust and grit burden from any furnace, oven, chimney, flue or industrial plant shall be taken when the appliance or plant is operating under normal running conditions and the period during which the sample is taken may include any period when customary peak loads are experienced. 2. The sample is to be taken in accordance with the isokinetic principle. 3. Not less than 2 increments comprising a sample are to be taken from points across the section of a chimney or flue where the velocity of the dust and grit emission is substantially equal. 4. The sample is to be collected in an inertial separator and followed by an efficient filter to retain the finer particles of dust and grit. (L.N. 262 of 1987) Cap 311B Sched 4 METHOD OF TAKING SAMPLE OF LIQUID FUEL [regulation 6(2)(c)] 1. Before any sample of liquid fuel is taken, a quantity of liquid fuel not less than the fuel consumption of the burner at its full rated capacity for 5 minutes shall be run off or consumed. 2. A sample may be taken- (a) at the burner tip or point of ignition with the furnace, oven or industrial plant not in operation, but with the preheater in commission and fully warmed up; or (b) when the furnace, oven or industrial plant is in operation, from a suitable test draw-off cock situated at the fuel supply line as close as practicable to the point of ignition. Cap 311B Sched 5 METHOD OF DETERMINING TEMPERATURE OF LIQUID FUEL [regulation 6(2)(d)] 1. The temperature of liquid fuel at the burner tip or point of ignition may be determined by- (a) a mercury-in-glass bulb thermometer; (b) a resistance bulb thermometer; or (c) any other means approved by the Authority. (17 of 1983 s. 50) 2. In the event of dispute, it shall be sufficient to prove accuracy of measurement to a tolerance of not more than one degree Centigrade- (a) in either direction at the operative temperature; or (b) by reference to 2 fixed temperatures such as the temperature of melting ice procured from distilled water and the temperature of boiling distilled water corrected for atmospheric pressure. Cap 311B Sched 6 LIMITS OF EMISSION OF DUST AND GRIT [regulation 10] 1. If a furnace, oven or industrial plant is burning solid fuel at a rate not exceeding 1000 kg per hour, or if any boiler has a maximum continuous rating not exceeding 7600 kg of steam per hour- (a) the total grit burden shall not exceed 33% of the total dust and grit burden; and (b) the total emission of dust and grit shall not exceed 1.0% of the total fuel fired.2. If a furnace, oven or industrial plant is burning solid fuel at a rate exceeding 1000 kg per hour, or if any boiler has a maximum continuous rating exceeding 7600 kg of steam per hour- (a) the total grit burden shall not exceed 20% of the total dust and grit burden; and (b) the total emission of dust and grit shall not exceed 0.5% of the total fuel fired.3. A furnace, oven or industrial plant shall not emit during each hour when the furnace, oven or industrial plant is consuming liquid fuel at the rate specified in the first column of the Table, dust or grit in excess of the percentage of the total fuel fired specified opposite thereto in the second column of that Table. 4. If more than one furnace, oven or industrial plant is connected to a common chimney or flue the total permitted limit of dust and grit burden shall not exceed the sum of the permitted limits for each furnace, oven or industrial plant so connected.
