The specification of test furnace is different with the difference of tested burner rating scope.The internal diameter of different size test furnace and smoke pipe quantity and size see the following form.Choosing of following parameter is optimum embodiment having taken all factors into consideration under the factors such as suitable power scope, floor space and investment cost of test furnace.
The different test furnace diameter of table 1 lower smoke tube size and quantity
How much of table 2 test furnaces and thermal parameter
Below to be applicable to that the thermal power scope is that the burner of 1200～3280kW, the test furnace that internal diameter is 0.8m are the test furnace structure that example specifies the application, is applicable to that the burner test furnace of other thermal power scope has similar structure.
Fig. 2 has represented that internal diameter is the concrete structure of the test furnace of 0.8m.Test furnace mainly is made up of body, flow of flue gas pipeline, cooling water circulation line, adjusting device, aided measurement device, safety control.Wherein, body comprises: front wall 01, combustion chamber 03, back wall 06, base 32.The flow of flue gas pipeline comprises: inlet plenum 02, discharge chamber 05, fume pipe 07, chimney 22, smoke regulating valve 24.The cooling water circulation line comprises: flexible hose 18,19,20,21, inlet and outlet pipe and flow control valve 28,29 thereof.Adjusting device comprises: slidably back 04, regulating handle 30,31 etc.Aided measurement device comprises: measure interface 10,13,14,23,34, thermometer 16,17, peephole 33.Safety control comprises: air bleeding valve 09, diffuse valve 11, pressure gauge 12, draining valve 15.
Front wall 01, back wall 06 all adopt heat-insulating material, with prevent at mobile burner and when regulating slip back the personnel that cause scald.Slidably back 04 is made up of ring-like dish 26 in outside and inner ring-like dish 27, and inside and outside dish inside all is full of cooling circulating water and can independent regulation.In order to realize regulating accurately, slip back 04 and the combustion chamber 03 inner rigid mechanical syndeton that adopts; Adopt flexible hose 18,19,20,21 to be connected with inlet and outlet pipe, guaranteed the quick, light of adjusting simultaneously.Thereby move the size that outside ring-like dishes 26 can be regulated combustion chamber 03 by handle 30, can change the pressure of combustion chamber 03, move the pressure that inner ring-like dishes 27 also can change combustion chamber 03 by handle 31 simultaneously by the smoke regulating valve in the chimney 22 24.According to the experiment needs, also can test the operation conditions of burner under condition of negative pressure by the air-introduced machine 35 of opening test furnace chimney upstream.
Before the test, check whether front wall is fastened, and whether all valves place the enable possition, each is measured interface and guarantees not to be plugged, and opens cooling circulating water then, starts burner.
In the test process, tested burner is mounted on the front wall 01 by flange, is lined with heat insulation asbestos between burner and the front wall 01.Power bracket according to tested burner, in conjunction with used test stove specification, calculate the theoretical length size of combustion chamber 03 according to formula (1), move the length of the position of back 04 slidably regulating the combustion chamber, pressure to appropriate value by handle 30 and 31 then, fuel that burner combustion is required and air are by inlet plenum 02 03 burning in the combustion chamber, when measuring forward flame, the flue gas that burning produces leads to atmosphere through discharge chamber 05, chimney 22.
In the burner combustion process, the measurement of back pressure can record by measuring interface 14 connection device for pressure measurement, connect the flue gas measuring instruments by the test interface on chimney 22 23, can measure the parameters such as content, flue-gas temperature, blackness of exhaustion of CO, CO2, NO/NO2/NOx in flue gas this moment.
The heat that burner produces in running is taken away by the cooling circulating water in the test furnace, be full of cooling circulating water in test furnace body, the slip back, the water inlet of cooling water, leaving water temperature can be observed by thermometer 16,17, and the water-in and water-out flow can be regulated by valve 28,29.
Whether burner flame in running is set up, and length of flame, color, flame status etc. can be observed by the peephole 33 of test furnace side.
The hydraulic pressure of cooling circulating water can observe by pressure gauge 12 in the test furnace, and the pressure of combustion chamber 03 can record after measurement interface 34 samplings by peephole 33 sides.The part steam that produces in the test furnace can discharge by air bleeding valve 09.If when the hydraulic pressure in the test furnace surpasses setting value, diffusing valve 11 will be opened, and test furnace is played the safeguard protection effect.Diffusing valve 11 outlets must be connected with the sewer pipeline, can prevent to scald when hot water from discharging operating personnel like this.
Test furnace is when test forward flame, dismountable back-up ring 08 must be installed in inlet plenum 02 to flow out through fume pipe 07 to stop flue gas, in this case, outside ring-like dish 26 and inner ring-like dish 27 are forbidden in the closed position, so that flue gas can be discharged through discharge chamber 05.When measuring reverse flame, must in inlet plenum 02, shift out back-up ring 08, in this case, when the ring-like dish 26 in outside and inner ring-like dish 27 were in the closed position, all flue gases arrived discharge chamber 05 back from fume pipe 07 and discharge from chimney.
In burner startup or test process, especially when the temperature of cooling circulating water remained on below 65 ℃, the steam in the flue gas will produce condensed water at the discharge chamber of test furnace.Condensed water in the flue gas is by draining valve 15 discharge frequently.
The length of burner hearth can be adjusted in the mobile slidably position of back 04, thereby can determine the power-back pressure curve map of burner.
Test finishes, and turns off cooling circulating water.
This test furnace can be regulated arbitrarily in certain power bracket internal furnace length, can the burner of different capacity section be detected, and can be by moving slidably back or special-purpose blast control valve adjustment burner hearth back pressure, pressure is adjustable from negative pressure-malleation.
