What are the 3 main types of consumers aim of this work is to explain the technique implemented and to give an idea of the wide range of applications that it can have, underlining its simplicity, its reliability and the low costs of the equipment needed. El objetivo de este trabajo calculate equivalence ratio combustion describir la técnica implementada y presentar su gran potencial de aplicabilidad.

The growing trend to use fossil fuels is causing serious social and economical problems, and geopolitical instability and pollution. The main environmental problem is the global warming. According to the Instituto de Planiicación y. This territory is inhabited by 1. In this work a real time diagnosis method of the biomass gasiication process in a downdraft reac -tor is presented.

The method is based on the. The diagnosis model can be an im-portant module of the control system to optimize the plant performance. Due to the simplicity and the low cost of the ins -trumentation needed to implement the method, it is underlining the potential of this tool. This can. Combustion processes in real systems can be mo-deled by non-dimensional or dimensional models.

The main objective of these mathematical appro-aches is to predict the gas composition and tem-perature at the outlet or through the whole length of the combustion device. This kind of models. In the case of incomplete com -bustion, additional data such as CO, NOx and un-burned hydrocarbons concentrations are required to obtain accurate results. These studies can be. But a diagnosis model of the biomass gasii.

A similar. They investigated. Majanne et al. The model can detect some faults and give information about the ope-ration of the process. By manipulating some equations used in predic-tive models it is possible to determine the input of such models air-fuel ratio from the measured outputs. This is the philosophy of a diagnostic model, being also possible to calculate some. In addition, since the con -centration of the more relevant gaseous species in the producer gas is high, it is not necessary an extreme precision of the analyzers and costs are widely affordable.

Moreover the diagnostic method proposed in this work only required the. The gasiier is an open top downdraft ixed bed reactor with an. Figure 1. Producer gas passes through a ilter to gas cleaning. The reactor and ilter work in a. The producer gas is intended to fuel an internal combustion engine, but in this test the gas is burned in a continuous burner. An optical pyrome-ter is used to calculate equivalence ratio combustion the temperature at the reac-tor core.

Equipment for low rate measurement is located at the tar ilter outlet and consists of a pressure. The pressure drop is mathematically related to the. Pressure measurements are not considered to be relevant as the system is not pressurized. Thus the small pressure drops along the lines are ne-glected and in calculations pressure is assumed to be at its atmospheric value. The gas analyzer system is compo-sed of infrared analyzers for CO, CO 2 and CH 4a thermal conductivity analyzer for H 2 and an elec-trochemical analyzer for O 2.

As the gas specimen is supposed to be tar and water free there is no need for humidity and tar detection devices. The calculate equivalence ratio combustion system described above cons-titutes all that is needed to carry out calculations. All data are collected by a PC acquisition board in order to be shown, stored and processed by a. The general chemical reaction process in the pro-ducer neglecting tars, carbon in the ash and minor compounds is expressed by the equation 4.

Five additional equations are obtained correspon -ding to the expressions of molar fractions for the gases that are measured experimentally, equa-tions 9 to It represents the amount of ini -tial water that reacts. Other possibility is to use only four analyzers and calculate the unknown measurement using the equation 28 derived from the expression of the checking parameter. When the composition of the dry producer gas is known, it is possible to calculate the density of.

So the gas low rate and the biomass rate can be known, see. Alternatively, the heating value can be esti -mated from the ultimate analysis of biomass, by. Which requires data obtained from the gas com-position analysis and the biomass comcom-position. This study is summarized in Figure 2. The graphs. Equivalence ratio with respect to the value of each measurement.

This point was de-termined by the rounded average measurements. It is important to take into account that this con -clusion is valid in the case of an error in the mea-surement system, but it is not probably valid for a real increment of CO concentration as the H 2 concentration would also be augmented. A test was performed using pine pruning bio-mass, with an empirical formula C 1 H 1.

CO and H 2 concentrations were constant except in the last part of the test, from s to s and from s until the test end. The bed reactor underwent a problem due to ash agglomeration. CO 2 and CH 4 had a similar. Once the general reaction coeficients are calcu -lated, the concentration evolutions can be imme-diately obtained. They are iteratively corrected discounting the O 2 and the corresponding N 2.

A reason for calculate equivalence ratio combustion low eficiency can what is an it business relationship manager found. After This is conirmed in Figure 5 where the thermal power of gasiier, the biomass mass low rate and the producer gas low rate are shown. At the beginning, mass low of producer gas reached. The temperature evolution was similar to the producer gas mass low rate.

The most interesting application of the procedure, apart from direct process analysis and check up, is the possibility of obtaining correlations among the calculate equivalence ratio combustion relevant parameters, which synthesi-zes the plant operation characteristics analyzed, such as gas composition analysis, equivalence.

In Figure 6a it is possible to appreciate the effect that equivalence ratio has on eficiency and. Tendencies were similar but the water decomposition showed a bigger calculate equivalence ratio combustion. Figure 6b shows the concen -tration trends of hydrogen, carbon monoxide and methane. Methane and hydrogen calculate equivalence ratio combustion with equivalence ratio. The carbon monoxide seemed to be quite independent from the equivalence ratio.

The hydrogen produced by water decomposition is used for methane and hydrogen production. The most important pa-rameters can be obtained and monitored in real time. A pro -ducer malfunctioning can then be detected when. Water decomposition. Fina -lly, an equivalence ratio increase is accompanied by a higher methane concentration and a lower hydrogen concentration.

The methodology presented here can be easily extended in case of having more detailed infor-mation about the hydrocarbon composition in the producer gas, such as provided by a. The diagnosis model developed is a powerful tool, because it is possible to calculate in real. Moreover, the model is useful for control, monitoring and fault detection in the biomass.
