Claims
- 1. Apparatus receiving a source of air and a sulfur-bearing source for conditioning the gas within an electrostatic precipitator of an industrial plant, comprising:
- a sulfur means having an output and an input, said sulfur means communicating with said sulfur-bearing source and said source of air, for at least providing gaseous, oxidized sulfur;
- a supply of liquid, oxidized sulfur, said sulfur means comprising evaporator means communicating with said supply of liquid, oxidized sulfur for evaporating it;
- converter means having an outlet and having an inlet communicating with the output of said sulfur means for converting said gaseous, oxidized sulfur into a conditioning medium;
- sensing means connected to said outlet of said converter means for providing a converted temperature signal signifying the temperature of said outlet of said converter means;
- modulation means connected to said sulfur means and said sensing means for varying the energy flow rate associated with the airflow from said source of air into said apparatus in response to said converted temperature signal; and
- delivery means connected to said outlet of said converter means for delivering said conditioning medium to said precipitator.
- 2. Apparatus according to claim 1 further comprising:
- mixing means communicating with said source of air and said evaporator means for mixing air from said source of air and evaporated, oxidized sulfur from said evaporator means, said mixing means being operable to deliver its mixture to said converter means.
- 3. Apparatus according to claim 2 wherein said modulation means comprises:
- airheating means coupled between said source of air and said mixing means for heating and delivering air from said source of air to said mixing means.
- 4. Apparatus according to claim 3 further comprising:
- parametric means coupled to said industrial plant for providing a parametric signal signifying at least one operating parameter of said industrial plant, said modulation means being operable to vary the energy flow rate associated with the airflow from said source of air to said mixing means in response to both said converted temperature signal and said parametric signal.
- 5. Apparatus receiving a source of air and a sulfur-bearing source for conditioning the exhaust gas flowing in an exhaust stage of an industrial plant including an electrostatic precipitator and an exhaust stack, comprising:
- a sulfur means having an output and an input, said sulfur means communicating with said sulfur-bearing source and said source of air, for at least providing gaseous, oxidized sulfur;
- parametric means coupled to said exhaust stage of said industrial plant for providing a parametric signal signifying at least one operating parameter associated with the handling of said exhaust gas of said exhaust stage of said industrial plant, said operating parameter corresponding to the demand made on said precipitator by said gas;
- throttle means connected to said sulfur means for varying the mass flow rate of said gaseous, oxidized sulfur leaving said sulfur means, in response to said parametric signal; and
- delivery means coupled to said output of said sulfur means for delivering said conditioning medium to said precipitator.
- 6. Apparatus receiving a source of air and a sulfur-bearing source for conditioning the exhaust gas flowing in an exhaust stage of an industrial plant including an electrostatic precipitator and an exhaust stack, comprising:
- a sulfur means having an output and an input, said sulfur means communicating with said sulfur-bearing source an said source of air, for at least providing gaseous, oxidized sulfur, said sulfur bearing source comprising a supply of liquid, oxidized sulfur, said sulfur means comprising evaporator means communicating with said supply of liquid, oxidized sulfur for evaporating it;
- parametric means coupled to said exhaust stage of said industrial plant for providing a parametric signal signifying at least one operating parameter associated with the handling of said exhaust gas of said exhaust stage of said industrial plant, said operating parameter corresponding to the demand made on said precipitator by said gas;
- throttle means connected to said sulfur means for varying the mass flow rate of said gaseous, oxidized sulfur leaving said sulfur means, in response to said parametric signal; and
- delivery means coupled to said output of said sulfur means for delivering said conditioning medium to said precipitator.
- 7. Apparatus according to claim 6 further comprising:
- mixing means communicating with said source of air and said evaporator means for mixing air from said source of air and evaporated, oxidized sulfur from said evaporator means, said mixing means being operable to deliver its mixture to said delivery means.
- 8. Apparatus according to claim 7 further comprises:
- airheating means coupled between said source of air and said mixing means for heating and delivering air from said source of air to said mixing means.
