Definitions

  • the invention relates to a steam generator with a Furnace downstream radiation part and one adjoining convective part, the latter essentially Consisting of cascaded flue gas side Touch heat exchanger, superheater and economizer, which for direct selective catalytic reduction (SCR process) of nitrogen oxides (NOx) in the waste gas from waste incineration plants (KVA) is used, the NOx catalyst is fed directly with the hot smoke gases, so is arranged in the circuit before the scrubber.
  • SCR process selective catalytic reduction
  • NOx emissions from thermal waste incineration plants must not exceed legally prescribed values.
  • NOx emissions which are generally between 300 and 450 mg / m 3 .
  • primary firing measures and / or more effective exhaust-side secondary measures are used, the secondary measures being the SNCR process (selective non-catalytic reduction) and the SCR -Procedures (selective catalytic reduction) are available.
  • the NOx reduction takes place thermally by the reducing agent (ammonia or urea) in one Temperature range from about 900 to 1100 ° C in the furnace or Boiler part is injected.
  • the reducing agent ammonia or urea
  • the NOx catalyst is provided in front of the scrubber in newer circuits. It is then fed directly with the hot flue gases, so that the exhaust gas does not have to be reheated after washing.
  • the catalytic converters With prior dedusting ("direct low dust” switching) to residual dust contents below 10 mg / Nm 3 , the catalytic converters achieve a service life similar to that in the switching systems after exhaust gas scrubbing.
  • the electric filter (e-filter) for dedusting can also be arranged after the NOx catalyst ("direct high dust" circuit).
  • the gas temperature in front of the NOx catalytic converter as constant as possible on a predetermined one Value, for example 350 ° C.
  • the optimal operating temperature the catalyst is at 320 to 350 ° C. (K.J. Thomé-Kozmiensky: Thermal waste treatment. EF publishing house für Energy- undmaschinetechnik GmbH, 2nd edition, 1994, p. 555-557). This bandwidth can be used depending on the Catalyst even larger, e.g. is one at one Operating temperature of 280 ° C working catalyst in one Waste incinerator known.
  • the gas temperature in a conventional KVA boiler has the following values in two different operating cases: Operating case Gas temperature in ° C after Superheater Evaporator Economizer Dirty at full load 461 343 237 Part load clean 370 290 190
  • Control devices are also from the prior art known, with which an almost constant Gas temperature can be reached.
  • DE 42 18 016 A1 for example, a multi-part economizer described, the Heating surfaces are connected in series, and the shut-off devices which has water side at the entrance of the individual switchable heating surfaces are arranged. The heating surfaces water flows through one after the other.
  • this device it is possible to lower the flue gas temperature safe at a minimum value at the outlet of the steam generator to avoid.
  • a disadvantage of this device is that the Water at low temperatures flows through heat exchanger surfaces become. The flue gas temperature is therefore in the control heating surface necessarily less than the evaporation temperature of the water, evaporation of the water is not possible (Water hammer).
  • a steam generator is known from US 4 160 009, in which a catalyst is arranged between two economizers is. These economizers each have constant, unchangeable heating surfaces. To control the flue gas temperature a gas bypass is used in front of the NOx catalytic converter, which is relatively expensive.
  • the invention tries to avoid all these disadvantages. you is based on the task of developing a steam generator, for SCR process circuits in which the NOx catalyst in front of the washer directly with the hot smoke gases is loaded, can be used, with relatively little effort the gas temperature in front of the catalyst on an approximate constant, predetermined value can be kept.

  • this is the case with a method of operation of the steam generator in that the temperature of the Flue gases immediately before they enter the NOx catalytic converter is measured and a dependent on the level of this temperature Number of lines (11b) that can be shut off from the water circuit is completed. This creates one or more sections of the economizer completed before the catalyst from the water cycle and part of the heating surface becomes inactive.
  • the advantages of the invention include that regulating the gas temperature upstream of the NOx catalyst is relatively easy to use and is guaranteed an approximately constant admission temperature of the NOx catalytic converter works optimally and has a long service life.
  • the invention can be used both in "direct-low dust" direct high dust circuits are also used, i.e. the e-filter can be arranged either before or after the economizer be.
  • the economizer in the boiler components upstream of the catalytic converter are designed so that during operation "Part load clean" the inlet temperature of the flue gas in the economizer upstream of the catalytic converter greater than / equal to the operating temperature of the catalyst.

  • the economizer in front of the catalytic converter 2a is designed in such a way that Partial evaporation can occur. It’s so big that in the "full load dirty" operating condition the inlet temperature of the flue gas 19 in the catalytic converter 5 is less than or equal to is the operating temperature of the catalyst 5.
  • the economizer in front of the catalytic converter 2a in the steam generator 1 upstream components, such as superheater 9, contact heat generator 18 ("protective bundle", which is first acted upon by the flue gas 19 ), empty trains 8, are designed so that during operation "Part load clean" the inlet temperature of the Flue gas 19 in the economizer in front of the catalyst greater than / equal is the operating temperature of the catalyst.
