Abstract
The utility model discloses a gas calorific value measuring burner based on firing method, including burning cavity, connection burning cavity top is surrounded heat exchanger coil around it, is connected in breather pipe and two ignition spools of burning cavity below through the ground connecting piece, breather pipe overcoat no. 1 surely fires the pipe, two intraductal ignition leads that lead to respectively of ignition lead, ignition lead tip installation ignition needle. The utility model discloses a gas calorific value measuring burner based on firing method can effectively light the gas and guarantee gas combustion after using gas calorific value measuring device.
Description
Technical field
The utility model belongs to metrological testing technology, relates to pin-point accuracy combustion method fuel gases calorific value measuring technique, is specially the burner that the fuel gases calorific value based on combustion method is measured.
Background technology
At present, combustion gas trade transaction metering method mainly contains energy meter and volume metering.Due to the difference of combustion gas constituent, the energy that the combustion gas of same volume produces is different, therefore volume metering fully can not reflect the inherent value of fuel gas, does not also meet the marketing rule of fair trade of fixing the price according to the quality, and is unfavorable for utilizing combustion gas resource scientifically and rationally; Energy meter then directly reflects the value of combustion gas.The method that fuel gases calorific value is measured mainly contains the indirect method of measurement and the direct method of measurement two kinds of modes.Indirect method mainly comprises vapor-phase chromatography and correlation method etc., they have the advantage that analysis speed is fast, real-time is good, to measuring the less demanding of environment, it is the measurement of caloric value method of applicable in-site measurement, but the indirect method of measurement is subject to the restriction of standard substance, uncertainty only reaches 0.5% and stability is not high.The direct method of measurement is that the heat that fuel gas buring discharges is delivered to certain heat-absorbing medium, determines fuel gases calorific value by the temperature rise measuring heat-absorbing medium.Direct method is mainly combustion-type calorimeter, and its accuracy of measurement is higher and can reflect the actual thermal value of combustion gas intuitively, but to measuring equipment and environmental requirement higher, therefore need to combustion gas provide one can for the environment of its safety and stability burning.
Utility model content
In order to solve the problem, the utility model provides the burner that a kind of fuel gases calorific value based on combustion method is measured.Concrete technical scheme is as follows:
The burner that a kind of fuel gases calorific value based on combustion method is measured, comprise burning cavity, connect described burning cavity top end and be looped around heat exchanger coil around it, be connected to snorkel below burning cavity and two igniting spools by ground web member, described snorkel overcoat one surely fires pipe, an ignition lead is led to respectively, described ignition lead end mounting points fire pin in described two igniting spools.
Further, burn below cavity and ground web member compact siro spinning technology.
Further, steady combustion pipe is placed in venting tube outlet place.
Further, between ignition electrode, spacing is not more than effective ignition distance.
After the burner that fuel gases calorific value based on combustion method of the present utility model is measured uses fuel gases calorific value measurement mechanism, effectively can light combustion gas and ensure fuel gas buring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the burner measured based on the fuel gases calorific value of combustion method.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the burner that fuel gases calorific value based on combustion method of the present utility model is measured, comprise burning cavity 1, connect described burning cavity 1 top and be looped around heat exchanger coil 2 around it, be connected to snorkel 4 below burning cavity 1 and two igniting spools 5 by frosted mouth web member 3, described ventilation mouth of pipe overcoat surely fires pipe 6, lead to an ignition lead 7 respectively in described two igniting spools, ignition electrode 8 is installed in described ignition lead 7 end.
During experiment, be placed in by this burner among inside and outside two-layer housing internal layer, housing internal layer fills heat-absorbing medium (pure water), its objective is to be absorbed in burner inner fuel gas buring reaction liberated heat.When heat-absorbing medium reaches uniform temperature, the combustion gas mixed according to a certain percentage in advance, oxygen and argon gas are passed into the snorkel in burner.Meanwhile, ignition electrode sends electric arc and lights a fire to combination gas, and combustion gas takes fire.For ensureing that the heat of combustion reaction is fully absorbed by heat-absorbing medium in combustion process, input air-flow slowly to snorkel.Argon gas in combination gas does not participate in reaction, and its effect is to be guarantee smooth combustion.
Burning chamber height, higher than the height of inside cavity flame, has a sufficient burning situation when ensure that combustion gas is burnt within it.
Arrange heat exchanger coil at burning cavity top end, the tail gas after burning passes into heat exchanger coil, and the heat of burning cavity inner exhaust gas is fully absorbed by heat-absorbing medium.Heat exchanger coil is designed to be coiled in the form around burning cavity, makes its compact conformation.The coil pipe number of turns is unsuitable very few, prevents coil outlets exhaust temperature higher than heat-absorbing medium temperature.
The mode that snorkel is connected by frosted mouth with igniting spool is connected with burning cavity.Frosted mouth is convenient to dismounting, is installed, and its design advantage is good airproof performance, effectively can intercept heat-absorbing medium and enter burning cavity, ensures that burning is carried out smoothly.
The design of ventilation mouth of pipe place surely fires pipe, ensures the stability of burning.
Logical ignition lead in two igniting spools in device, ignition electrode is installed respectively by mouth of pipe place.Ignition electrode adopts material that is high temperature resistant, corrosion-resistant and good in oxidation resistance.In order to ensure to produce electric arc between ignition electrode and have enough energy to light combustion gas, its spacing can not be greater than effective ignition distance.
Above-mentioned example is only for the citing done is described, the restriction not to embodiment.For those skilled in the art, other multi-form change or variations can also be made on the basis of the above description, these thus the apparent change of extending out or variation be still among the protection domain of this creation.
