4、N The Canadian Standards Association provides certification services for manufacturers who, under licence from CSA, wish to use the appro- priate registered CSA Marks on certain products of their manufacture to indicate conformity with a CSA Standard. CSA Certification for a number of products is pr

5、ovided on a voluntary basis in the interest of mainta-ining agreed-upon standards of quality, performance, interchangeability, or safety and, where appropriate, it forms the basis for accep- tance by inspection authorities responsible for enforcement of regulations. Where feasible, programmes will b

6、e developed for additional products for which certification is desired by producers, consumers, or other interests.

16、se of this Standard the definitions contained in the latest issue of CSA Standard B139, Installation Code for Oil Burning Equipment, shall apply. 3. GENERAL REQUIREMENTS 3.1 A nozzle shall be assembled as a unit and shall include all the com- ponents necessary for its normal function when used as in

17、tended. 3.2 The construction of a nozzle shall be such that parts can be readily reassembled in a proper manner after being dismantled to the extent needed for normal servicing. 3.3 The design shall be such as to prevent the entrapment of air pockets. 3.4 An integral filter or strainer shall be prov

18、ided. 3.5 The nozzle shall be designed so that, when the integral filter or strainer is removed for cleaning, all foreign matter (sediment or dirt) can be removed readily without the probability of being deposited in the nozzle. 3.6 A nozzle shall be designed to withstand, without rupture or permane

19、nt deformation, an impressed flow pressure equivalent to two times the rated pressure but not less than 500 psig. 3.7 The flow and spray rating marked on the nozzle shall be the rating at 100 psig unless another pressure rating is indicated on the nozzle. NOTES: 1. Standard flow rates in gallons (US

20、.) per hour, of nozzles are deemed to be: 0.40, 0.50, 0.60, 0.65, 0.75, 0.85, 0.90, 1.00, 1.10, 1.20, 1.35, 1.50, 1.65, 1.75 and 2.00. 2. Standard nominal spray angles of nozzles are deemed to be of the following: 30, 45, 60, 70, 80, and 90 degrees. 8 CSA STANDARD B140.2.2 3.8 Orifices and passages

21、shall be accessible for cleaning. 3.9 Oil passages shall be free from machine cuttings, burrs, or foreign matter including gum formations. 3.10 Nozzles shall be of good workmanship, specifically: (a) Mating parts shall fit properly; and (b) Parts shall be properly aligned. 4. CONSTRUCTION REQUIREMEN

22、TS 4.1 General 4.1.1 Nozzles, unless designed for a specific use, shall be mechanically interchangeable with other standard makes of nozzles. 4.1.2 Nozzles, when designed for mechanical interchangeability, shall be % inch plus or minus KG inch in length, as measured from the orifice tip to the shoul

23、der. 4.1.3 The shoulders of nozzles shall be machined to assure a positive seal with the nozzle adapter. 4.2 Materials the radiant heat of flame without excessive oxidation or corrosion. 4.2.1 The materials used for nozzles shall be capable of withstanding 4.2.2 The orifice body shall be of a suitab

24、le grade of stainless steel or of a material having an equivalent resistance to normal wear and accidental damage. 4.2.3 All parts of a nozzle shall be made of material having a melting point of not less than 1,000 F. 4.3 Filters or Strainers 4.3.1 The filter mesh size shall be at least 150 mesh for

25、 nozzles less than 1 gallon (US.) per hour, and at least 100 mesh for nozzles from 1 gallon (U.S.) per hour up to 2 gallons (U.S.) per hour. 4.3.2 Nozzle filters fabricated from porous bronze, pressed steel, or other materials, shall provide protection for the nozzle orifice equivalent to the protec

26、tion required in Clause 4.3.1. 4.4 Rated Capacity. The rated capacity tolerance range shall not be more than 10 per cent from the marked rating when tested in accordance with Clause 6. NOTE: For example, the tolerance may be minus zero per cent and plus 10 per cent, or minus 2 per cent and plus 8 pe

27、r cent. 4.5 Spray Angle. Nozzles of the same make, type and rating shall exhibit the following characteristics when tested in accordance with Clause 6: (a) Consistency of spray angle about the axis of the nozzle within (b) Concentricity of spray angle about the axis of the nozzle within 4.6 Spray Pa

28、ttern. Nozzles of the same make, type, and rating shall exhibit the following characteristics when tested in accordance with Clause 6: plus or minus 5 degrees; and plus or minus 5 degrees. PRESSURE ATOMIZING OIL BURNER NOZULES Rated Marked Capacity gph U.S. - 9 1 Distance from Face of Nozzle Inches

29、(a) Consistency of spray pattern; and (b) Uniform oil distribution. 5. MARKING 5.1 Nozzles shall be plainly marked in a permanent manner with the following : (a) The manufacturers name, trade name, or other recognized symbol of identification ; (b) The rated capacity in U.S. gallons per hour; (c) Th

30、e nominal spray angle in degrees; (d) The nominal spray type or pattern; (e) The pump pressure if the nozzle is rated at other than 100 psig. 6. TESTS 6.1 General supplied by the nozzle manufacturer. shall comply. determined at the distances indicated in Table 1 : 6.1.1 For the purpose of these test

31、s, the nozzle shall be as normally 6.1.2 At least three nozzles of each type and rating shall be tested; all 6.1.3 The angle of nozzle spray for the purposes of these tests shall be TABLE 1 MEASUREMENT OF SPRAY ANGLE 0.5 to 0.85 1.00 to 2.00 0.5 to 2.00 0.5 to 3.00 6.1.4 Tests shall be conducted at

32、the oil flow rate marked on the nozzle at 100 psig or at the rated oil pressure, and the test oil at a temperature of 70 to 80F at the nozzle except that subsequent retests shall be conducted at the original qualification temperature, plus or minus 1F. 6.1.5 Reference Fuel Oil. The test oil shall co

33、nform to grade No. 2 (ASTM Standard D396-67, Specifications for Fuel Oils) having these characteristics : (a) Viscosity - 35 k 1 SSU at 100 F; (b) Gravity - 32 to 38 API at 60 F. 6.1.6 For the purpose of these tests, the spray pattern of a nozzle shall be considered acceptable if the spray patterns

34、obtained from three similarly identified nozzles meet the requirements contained herein when tested in accordance with Clause 6. 10 CSA STANDARD B140.2.2 6.2 Rated Capacity. Each nozzle shall be subjected to a flow test and the rate of discharge shall be within the limits specified in Clause 4.4. 6.

35、3 Spray Angle and Spray Pattern 6.3.1 The spray angle and spray pattern shall be determined for each nozzle under flow conditions. NOTE: Since it is the intent to determine consistency of similurly-identi,fied nozzles from one production lot to the next, rather than compliance with absolute values,

36、such compliance is determined by comparison of results of the tests in Clause 6.3.1 to an miginally- established datum. For example, it is significant that the spray angle, as determined by these tests, be within acceptable limits of the angle of an original nozzle rather than that a nozzle marked “

37、60 degrees spray” actually spray at 60 degrees. 4.3.2 Each nozzle shall be mounted by its normal means of attachment with its axis vertical, spraying upward in a draft-free area.
