Definitions
- the invention relates to a method and a device for regulating the combustion characteristics of a gaseous fuel, and more particularly the calorific power conveyed by a current of gaseous fuel, including a stream of fossil fuel from natural gas type.
- the invention relates in particular to a regulation of a current of gaseous fuel distributed by a network of supply lines to industrial plants operating a thermal process, the regulation according to the invention preferably operating at the downstream end of said network, on the site of the industrial installation or just upstream of it.
- the industrial installations more particularly targeted are: glass installations using natural gas burners to ensure the melting (and possibly refining) of glass in the broad sense, that is to say of mineral compositions used to make flat glass (lines float), hollow glass (bottles, bottles), mineral wool from glass or rock type intended for thermal and / or acoustic insulation or glass fibers used for reinforcing materials of the type polymers, called reinforcing fibers or even textile fibers.
- the ovens have the most constant and uniform operating regime possible, one parameter among others, not negligible, being the properties of the fuel that powers the burners, including its calorific value.
- the distribution network supplies natural gas whose properties fluctuate, for various reasons, the most frequent is the fact that the network is supplied with natural gas from different properties by multiple sources of supply.
- a first mode of regulation consisted in playing on the flow of the fuel, by correcting its calorific value by high value in increasing its flow, or by low value by decreasing its flow with a non-combustible gas to decrease its flow, flow corrections occurring in the same proportions as the fluctuations observed in the calorific value of the fuel.
- This regulation mode allows maintain the heat flow entering the oven at its set value. Whether this regulation is done manually or automatically, the limits were quickly reached: indeed, it was observed that a simple correction of the calorific power of the incoming gas by modulation proportional flow failed to stabilize perfectly the oven speed, all other things being equal. This could be explained by the fact that variations in fuel flows at the level of burners are also causing changes in the way the combustion takes place, in the way the flame will develop above glass bath in particular.
- the object of the invention is to achieve a regulation which best preserves the stability of the operating regime from the oven, when the fuel is intended to supply the burners of a glass oven type oven.
- the object of the invention is a method of regulating ⁇ power heat ifique of a gaseous fuel stream of the fossil gas type comprising a majority combustible gas called ⁇ A ⁇ and circulating in a conduct. It consists in operating the regulation, at least in part, by controlled addition to the stream of at least one combustible gas called ⁇ B ⁇ of calorific value higher than that of ⁇ A ⁇ .
- the gas called ⁇ A ⁇ is methane CH 4 , the majority compound of the fossil gaseous fuel known under the term of natural gas, which is therefore the stream of gaseous fuel to which the regulation according to the invention preferably applies (the invention can also be applied mutadis mutandi to other streams of combustible gas, for example manufactured gas).
- the ratio C / H of the fuel without unit, which corresponds to the ratio of the total number of carbons on the total number of hydrogen of the fuel (for example, in the case of methane CH4, this ratio C / H is 1 ⁇ 4, or 0.25).
- B Va / (d) 1 ⁇ 2 , with Va the theoretical air necessary for the combustion of one m 3 of fuel, B being a dimensionless quantity if Va is expressed in normal m3 of air per normal m 3 of fuel.
- the invention therefore adopted a regulation ⁇ by high value ⁇ , that is to say making it possible to control the calorific value of the fuel by adjusting it towards higher values using a gas more ⁇ calorific ⁇ than the fuel, or more precisely more ⁇ calorific ⁇ than the majority gas of the latter.
- a gas more ⁇ calorific ⁇ than the fuel or more precisely more ⁇ calorific ⁇ than the majority gas of the latter.
- methane which generally represents more than 80% of natural gas, the minority compounds being for example traces of inert gas type N 2 or longer chain hydrocarbons.
- the regulation is done only using such a more calorific gas. Regulation does not modify the volume flow rate of the gas stream thus regulated, or only very little.
- This type of regulation brings many advantages.
- the advantage main is that there is a marked improvement in the stability of operation of the furnace equipped with burners supplied with fuel thus regulated.
- the explanation that we can put forward is that this mode of regulation allows to control the incoming calorific flow without modifying significantly the volume flow and therefore without modifying the properties flame aeraulics (length, speed, ).
- Another important and completely unexpected advantage relates to the emission of so-called NO x gases by the ovens whose burners are thus regulated: it has been observed effectively that an upward regulation operated as in the invention allows a significant reduction in NO x emissions from ovens, which is extremely positive for the environment.
- the gas ⁇ B ⁇ is chosen from hydrocarbons having at least two carbons, whether they are saturated or have at least one unsaturation. It can be linear or branched. Preferably, it contains from 2 to 6 carbons and is in particular in the form of propane or of n-butane. In fact, we prefer to choose a fuel in gaseous form without further treatment in pressure and temperature conditions where the current is fuel to be regulated. The cost of the chosen hydrocarbon also comes into play and its availability.
- petroleum gas i.e. from petroleum refining, especially based on propane or n-butane (it being understood that these so-called petroleum gases, if they have a constituent majority such as propane or butane can also contain other minority elements, for example propene, butene, ..., as is well known).
- the response times of the mentioned loops above are, for example, a few seconds for the so-called loop ⁇ fast ⁇ , and 1 to 3 minutes for the so-called ⁇ slow ⁇ loop if using a comburimeter up to 5 to 15 minutes if using a chromatograph in gas phase.
- a measurement to within 1 to 2% with a comburimeter and with a chromatograph a measurement to 0.5 to 1%.
- the chromatograph is therefore a little more precise, but does not allow continuous measurement.
- use Chromatograph allows them to be taken into account without problem.
- the invention also relates to the application of the method and the previously described device to regulate the calorific value a fuel stream in a pipe at the end a power network with one or more sources of supply, and more particularly of a current of fuel in a line supplying fuel to one or several burners used in an industrial installation of the type glass installation.
- the invention also relates to the glass furnace itself, equipped burners at least part of which is supplied with fuel regulated according to the invention.
- Simplicity means that regulation takes place on the pipe main supplying fuel to all the burners of the installation, nothing, however, prevents regulation on secondary pipes, at the level of each of the burners or only at the level of certain of them.
- the invention however applies more generally to any type of glass furnace using natural gas burners, such as so-called loop regenerators, the ovens for flat glass operating without regenerators and generally using oxidant burners under form of oxygen (an example of which is described in patent EP-0 650 934). They may be ovens also intended for the manufacture of hollow glass of mineral wool or reinforcing yarn.
- the ovens that can benefit from the invention can also use so-called "submerged” gas burners, that is, configured so that the combustion flame or the gases from combustion develop within the batch material in fusion (an example being described in patents US-3,260,587 and US-3 738,792).
- the invention proposes to regulate the Wobbe index (or the PCS) of the flow of natural gas in this pipeline on the industrial site.
- a tapping where we will be able to take a sample at a given frequency of fuel to measure its properties (the Wobbe index or the PCS), either directly using a measuring device of the type described in the aforementioned patent EP-0 326 494 A1, either using a gas chromatograph.
- the optimal measurement frequency is three minutes, which allows you to react very quickly to any rapid fluctuation in the calorific value of the natural gas supplied, and to control the efficiency of the driving regulation.
- a pipe is provided secondary propane injection fitted with a flow control means, this secondary pipe being supplied either by a network of propane distribution either by a propane storage enclosure (the propane in question is commercial propane, derived from the refining of petroleum and which can contain, for example, up to 10 or 20% of other minority compounds, usually other hydrocarbons such as propene).
- IT means control both the measurement means of Wobbe index of natural gas flow and means of flow control of propane: a set value of Wobbe index (or of PCS) maximum.
- IT resources by comparison between the index of Wobbe (or the PCS) measured and that of the setpoint, control so continues to increase or decrease the flow rate of propane injected in the main line, so that the measurement is equal to the instructions.
- the regulation according to the invention promotes a drop in the specific energy consumption of the oven: increase the efficiency the thermal effect of the oven reduces its operating cost and thus cover, at least in part, the additional cost linked to the injection of propane.
