Definitions
- the invention relates to a method for burning lumpy fuel, in particular limestone, in a regenerative shaft furnace, with at least two interconnected by a transfer channel furnace shafts in which the kiln an upper preheating, a central combustion zone and lower cooling zone passes, wherein Nerbrennungs Kunststoff in Area of Normérmzone and cooling air in the area of the cooling zone zugeiuhrt and a supply of fuel gas with a lower calorific value of less than 7.5 megajoules (MJ) per m 3 n is periodically changing to one of the shafts over burner lances.
- a transfer channel furnace shafts in which the kiln an upper preheating, a central combustion zone and lower cooling zone passes, wherein Nerbrennungs Kunststoff in Area of Norissermzone and cooling air in the area of the cooling zone zugeiuhrt and a supply of fuel gas with a lower calorific value of less than 7.5 megajoules (MJ) per m 3 n is periodically changing to one of the shafts over burner lance
- Regenerative shaft ovens of this type which are also referred to as MAERZ ovens, are characterized by a particularly high efficiency compared to shaft ovens of other types.
- lean gas ie a Nerbrenstedsgases with relatively low calorific value, such as by-product in metal or biogas with a lower calorific value of less than 7.5 megajoules (MJ) per m 3
- the process parameters of regenerative shaft stoves adversely affect and their efficiency is much lower due to much higher amounts of exhaust gas and exhaust gas temperatures.
- higher exhaust gas temperatures require additional measures, for example, to prevent overheating downstream filter systems by exhaust gas cooler or by admixing fresh air.
- the use of lean gas through reduced incorporation of sulfur results in improved product quality in this respect.
- the invention has for its object to find a Nerfahren of the type mentioned, which avoids the disadvantages mentioned and thus with good thermal efficiency, the use of a fuel gas with relatively low lower calorific value of less than 7.5 MJ / m 3 n with good product quality allows.
- the at the mouths 17 of Brennla zen 9 forming flames get preheated combustion air, as it flows through preheated fuel during the previous period of operation.
- the preheating of the fuel in the preheating zone 8 takes place in each adjacent shaft (2) by the combustion gases overflow after passage of the combustion zone 18 via a connecting channel 19 in the adjacent shaft 2 and leave this as exhaust gas upward according to the arrow 20.
- the preheating of the fuel gas takes place in a heat exchanger 21 in heat exchange with a branched off from the connecting channel 19 via a line 22 in a relatively small amount of hot gas stream, which is then discharged to the exhaust stream according to the arrow 20.
- the guided through the heat exchanger 21 line 23 can be switched when changing the mode of operation to the adjacent shaft 2 via a valve 24 to the burning lances 25 of the adjacent shaft 2. In this way, an economic operation of the furnace 3 with lean gas with a lower calorific value of less than 7.5 MJ / m 3 and, for example, 4 MJ / m 3 is possible.
- a preheating of the fuel gas can alternatively or additionally to preheating in the heat exchanger 21 in the preheating by the preheated combustion air there by the surface of the fire lances 9,25 at least on its outside, for. is carried out enlarged by ribs.
