Large Semifluid Burner

The Large Semifluid Burner (LSB) is an EV tier multiblock for generating power from semifluid fuels. The LSB is a direct upgrade from singleblock semifluid generators because it has much higher fuel efficiency and can output more than 1A of power. However, the LSB must be supplied with 2,000 L/h of lubricant to run, and optionally 80 L/s of oxygen to boost the machine. Boosting is highly recommended because it triples the maximum power output and increases the fuel efficiency from 100% to 150%. Power is extracted from a 4A dynamo hatch on the back of the machine. Do not exceed the maximum EU/t of the dynamo hatch or else it explodes. Save on fuel by automatically toggling the LSB with an RS latch connected to a Lapotronic Supercapacitor.

The LSB has no tiered components. The maintenance hatch, muffler hatch, and input hatch(es) may replace any machine casing anywhere on the structure. A quadruple input hatch is recommended for inserting all the necessary fluids. The dynamo hatch is limited to the center casing on the very back of the structure and cannot be greater than 4A. Use the Multiblock Structure Hologram Projector to visualize/build the structure.

Structure

• Controller: Front center, 2nd layer
• 16-21 Stable Titanium Machine Casing
• 8 Engine Intake Casing
• 2 Steel Gear Box Casing
• 1 Dynamo Hatch: Back center casing
• 1 Maintenance Hatch: Any machine casing
• 1 Muffler hatch: Any machine casing
• 1+ Input Hatch: Any machine casing

Wallsharing

LSBs may wallshare each of their sides to save on casings and buses/hatches. That includes the input hatch for the necessary fluids.

The LSB generates power from semifluid fuels. The following table lists the available options and their densities (EU/L). The most popular options are creosote oil, glycerol, and heavy fuel because they are the byproducts of benzene production, bio diesel production, and oil refining respectively.

The LSB has two operating modes, listed below. The machine automatically switches between them based on the available inputs. Boosting is highly recommended because it triples the maximum EU/t and increases the fuel efficiency from 100% to 150%. The oxygen is not difficult to sustain--simply build a sugar beet or sweed farm and electrolyze the sugar.

Default

• Inputs: Fuel + 2,000 L/h lubricant
• Output: Maximum 2,048 EU/t at 100% fuel efficiency.

Boosted

• Inputs: Fuel + 2,000 L/h lubricant + 80 L/s oxygen
• Output: Maximum 6,144 EU/t at 150% fuel efficiency.

The LSB also has its own efficiency value that is directly proportional to the power output of the machine. The efficiency of the LSB increases linearly while the machine is active and almost immediately resets back to 0% while the machine is idle. It takes 33s (default) or 100s (boosted) to reach maximum efficiency. This means the LSB should run for as long as possible but not forever because additional EU is voided once the dynamo hatch is full. View the current efficiency by using a Portable Scanner on the controller, or by looking at the efficiency value in WAILA.

Power is extracted from a 4A dynamo hatch on the back of the structure. Do not exceed the maximum EU/t of the dynamo hatch, or else the LSB will explode. Breaking the dynamo hatch or exceeding the total EU is perfectly safe; the LSB will not explode if an attached battery buffer or Lapotronic Supercapacitor (LSC) is full and there is nowhere for the EU to go. Any additional EU is simply voided. It is highly recommended to automatically toggle the LSB with a redstone RS latch to avoid wasting fuel--see the LSC page for a guide on setting that up.

• Fish oil, biomass, oil, and creosote oil are all valid fuels for the Large Combustion Engine too, but they are much better in the LSB.
