A heating, ventilating and air conditioning worker's servicing cart consisting of a base platform to which is mounted an axle holding two anterior wheels, two posterior platform legs, two pairs of upper platform uprights to the posterior pair of which and the platform legs there are attached handlebars with a top platform attached to the platform uprights and legs with cross braces to which recovery and refrigerant tank strapping is attached with pressurized tank strapping attached to the posterior pair and with brazen rod quivers attached to the posterior platform legs and with a recovery tank stabilizing ring affixed to the base platform as well as a recovery tank stabilizing plate and vacuum pump holding bracket both being affixed to the anterior pair of top platform uprights along with recovery tank support strapping with the plate being affixed below the holding bracket. an internal makeup water heater bundle, and means to introduce makeup water into said steam dome. 2. Apparatus according to claim 1 wherein said means to introduce makeup water into said steam dome is an internal makeup water header. 3. Apparatus according to claim 2 wherein said internal makeup water header is a pipe having spray nozzles. 4. Apparatus according to claim 3 wherein said spray nozzles are self adjusting. 5. Apparatus according to claim 3 wherein said spray nozzles are arranged to spray makeup water counter-current to flow of steam introduced by the steam inlet. 6. Apparatus according to claim 1 further including an internal makeup water header having air extraction means. 7. Apparatus according to claim 6 wherein said air extraction means is at the outlet of said internal makeup water heater bundle. 8. Apparatus according to claim 1 wherein said internal makeup water heater bundle comprises a plurality of straight or U-tubes. 9. Apparatus according to claim 1 wherein said internal makeup water heater bundle is located internal to said steam dome. 10. Apparatus according to claim 1 further including an internal makeup water heater having air extraction device or automatic air release valve at the outlet of said internal makeup water heater bundle. 11. Apparatus according to claim 10 wherein the said internal makeup water heater bundle comprises a plurality of straight or U-tubes located internal to said steam dome and containing an air extraction device or automatic air release valve at the outlet of said internal makeup water heater bundle; and said means to introduce makeup water into said steam dome is an internal makeup water header comprising a pipe having self adjusting spray nozzles arranged to spray makeup water counter-current to flow of steam introduced by said steam inlet. 12. A process for use in a power plant having a steam turbine and a condenser for condensing exhaust steam from said turbine comprising heating makeup water in a makeup water hearer bundle section within said condenser to a desired temperature; and introducing the resultant heated makeup water into exhaust steam from said turbine within said condenser. 13. The process of claim 12 wherein said desired temperature is approximately 5.0° F. below the saturation temperature of the turbine exhaust steam and is further heated upon introduction to said exhaust stream to the saturation temperature of the turbine exhaust steam. 14. The process of claim 12 wherein air liberated from said makeup water in said bundle section is automatically and periodically vented prior to introducing said resultant heated makeup water into said condenser. 15. The process of claim 12 wherein said resultant heated makeup water is introduced using spray nozzles in a direction countercurrent to said turbine exhaust steam. 16. The process of claim 15 wherein said spray nozzles are directed in a direction opposite to the flow of turbine exhaust steam. 17. The process of claim 16 wherein said spray nozzles are arranged so as to maximize the contact time between said turbine exhaust steam and said makeup water. 18. The process of claim 12 further including providing an oversized air cooling zone in said condenser so as to reduce vapor in air vapor mixture and improve venting. 19. The process of claim 12 further including providing a hooded air channel within said condenser so as to prevent dripping condensate contacting air vapor mixture. s securing said tubular subassemblies spaced apart between said support walls, the spaced apart tubular subassemblies defining a series of alternating catalyst-coated and uncoated channels. 2. The catalytic combustor according to claim 1, wherein said tubular subassemblies have a substantially rectangular cross section. 3. The catalytic combustor according to claim 1, wherein a top and bottom wall of said tubular subassemblies have a curved profile when viewed in cross section. 4. The catalytic combustor according to claim 1, wherein said tubular subassemblies further comprise a top, a bottom, and a pair of sides, said sides configured to fit in respective ones of said longitudinal grooves in said support walls. 5. The catalytic combustor according to claim 4, wherein said sides and said support walls define a plurality of apertures dimensioned and configured to permit airflow through said tubular subassemblies, in a direction substantially perpendicular to said tubular subassemblies. 6. The catalytic combustor according to claim 5, further comprising a first manifold adjacent to one of said support walls, and a second manifold adjacent to the opposite of said support walls; said first manifold being dimensioned and configured to direct air into said uncoated channels, in a direction substantially perpendicular to the elongated dimension of said tubular subassemblies, said second manifold being dimensioned and configured to receive air from said uncoated channels, and to direct the air towards said catalyst-coated channels. 7. The catalytic combustor according to claim 1, wherein said catalyst is selected from the group consisting of platinum, palladium, ruthenium, rhodium, osminium, iridium, flame-sprayed titanium dioxide, cerium oxide, vanadium oxide, and chromium oxide. 8. The catalytic combustor according to claim 1, wherein: said catalyst coated channels include a central portion defining a cross sectional area; and said outlet ends of said catalyst coated channels comprising a cross-sectional area smaller than said central portion's cross sectional area. 9. A catalytic combustor comprising: a plurality of tubular subassemblies, each of said tubular subassemblies having an inlet end, an outlet end, an exterior surface, and an interior surface, one of said surfaces having a catalytic surface coating; and means for supporting said tubular subassemblies in spaced relationship along substantially an entire length of said tubular subassemblies, and for defining a series of alternating catalyst-coated and uncoated channels, said means further comprising a longitudinal groove. 10. The catalytic combustor according to claim 9, further comprising: means for directing a first portion of air through said uncoated channels; means for mixing fuel with a second portion of air; and means for directing the resulting fuel-air mixture through said catalyst-coated channels. 11. The catalytic combustor according to claim 10, further comprising: means for mixing said fuel-air mixture with said first portion of air after passage of said first portion of air through said uncoated channels and passage of said fuel-air mixture through said catalyst-coated channels. 12. The catalytic combustor according to claim 9, further comprising: means for directing air into said uncoated channels; means for receiving air from said uncoated channels, and directing air received from said uncoated channels into said catalyst-coated channels. ering the turbine under the maximum braking power condition is maintained at least equal to a safety limit value calculated on the basis of geometrical characteristics and of limit values of operating parameters of the engine and of the turbocharger for the purpose of achieving the maximum braking power compatible with the safety of the engine and of the turbocharger.
