RTM 3.0

New Industrial Blast Furnace

• Added a new Industrial Blast Furnace for large-scale iron and steel production.
• Uses coke, pressurized hot blast, optional oxygen enrichment, limestone, and supplied heat.
• Produces recoverable Blast Furnace Gas, slag, and other realistic byproducts instead of simply consuming everything.
• Hotter blast air and oxygen enrichment can improve furnace performance.
• The previous small Blast Furnace is now the Metallurgical Furnace and remains useful for smaller-scale metallurgy and alloy production.

Power & Steam

• Rebalanced generator output, internal buffering, fuel use, and progression.
• Stirling generators now behave as heat engines instead of oversized batteries, with 10 kW and 40 kW default outputs.
• Reworked the small Steam Turbine into a 75 kW precision turbine instead of an overpowered early-game engine.
• Steam equipment now has clearer steam-grade limits across ordinary, hot, superhot, and ultrahot steam.
• Generator recipes now use more realistic mechanical, pressure, heat-transfer, winding, piston, and turbine components instead of arbitrary rare-material filler.
• Improved Diesel, industrial piston, gas turbine, turboshaft, solar, geothermal, RTG, and several other generator behaviors.
• The Wood Generator remains deprecated from normal progression.

Chemistry & Processing

• Major chemistry rebalance across acids, alkalis, ammonia, methanol, polymers, coolants, mineral processing, nuclear materials, water treatment, and other industrial chains.
• Chemical processes now conserve substantially more of their actual inputs, outputs, water, gases, residues, and reusable process fluids.
• Removed many old recipes that deleted materials or produced unsupported byproducts from nowhere.
• Chemical machines can retain partial process progress and fractional outputs instead of losing work between batches.
• Chemical Reactors now support up to 4 item inputs, 4 fluid inputs, 4 item outputs, and 4 fluid outputs.
• Chemical Reactor heating requirements are now handled through their actual powered operation rather than requiring nonexistent heater placement.
• Machines designed for external heating still require a deliberate heater interface.

Fluids & Piping

• Standard fluid ducts can now carry up to four configured fluids through the same line.
• Fluid identifiers can add or remove individual allowed fluids.
• Single-fluid branches can still filter a shared trunk.
• Existing single-fluid pipe setups remain compatible.
• Fixed several cases where changing fluid identifiers could destroy stored fluid.

Boilers, Air & Industrial Heat

• Boilers can now properly handle their shared heating processes, including blast-air heating and petroleum/coolant duties.
• Industrial Boilers can use either their internal burner or qualified external heat where appropriate.
• Added selectable ordinary-steam output to the Industrial Boiler alongside its existing hotter steam output.
• Increased compressor capacity for large-scale air processing.
• Improved atmospheric collection, compression, decompression, air separation, and isotope processing.
• Blast Furnace air grades now behave consistently and use one selected blast grade at a time with separate oxygen enrichment.

Machine Progression & Recipes

• Reworked many machine recipes around the equipment they physically represent: vessels, pumps, piping, drives, heat exchangers, pressure hardware, controls, rotors, and structural components.
• Updated construction for boilers, presses, rotary furnaces, mixers, crackers, crystallizers, air-processing equipment, casting equipment, and other industrial machines.
• Removed several arbitrary or dependency-heavy ingredients that did not fit the machine being built.
• Restored and corrected lubricant production from refinery products.
• Fixed numerous material-processing inconsistencies involving steel, stainless steel, bronze, solder, graphite, thermite, metal powders, nuggets, ores, and intermediate forms.

Machine Information & NEI

• Expanded machine tooltips and GUI information with installed power, efficiency, cooling, operating requirements, and current machine state.
• Added or improved NEI support for:
  • Blast Furnace
  • Compressors
  • Atmospheric processing
  • Air separation
  • Isotope separation
  • Boilers
  • Electrolysis
  • Chemical processing
  • Fuel-fired furnaces
• Fixed missing or misleading gauges, recipe pages, quantities, utility displays, and fractional outputs.
• Fixed the Cryogenic Distillation NEI page missing its background.
• Compressor pressure and operating-mode controls are now clearer and no longer overlap inventory controls.

Materials & Physical Accounting

• Expanded RealSim's material accounting so more recipes track actual mass, fuel value, process energy, and recoverable byproducts.
• Improved support for different material forms such as powders, nuggets, ores, polymers, fuels, and intermediate compounds.
• Corrected numerous recipes that duplicated, deleted, or incorrectly substituted materials.
• Solid fuels are now identified by their actual material role instead of simply treating anything with stored energy as valid fuel.

Fixes

• Fixed Electrolyser coproduct and Dairy condensate displays.
• Fixed mixed Electrolyser power budgeting.
• Fixed machines losing partial paid heating or processing work.
• Fixed several over-capacity inventories and energy buffers incorrectly deleting stored resources.
• Fixed generator export and storage edge cases.
• Fixed Compressor mode synchronization.
• Fixed various invalid recipe ingredients, machine recipe displays, fluid handling issues, and registration errors.
