About this simulation
A 90-minute, 4-round basic Express simulation for Spanish vocational training (Formacion Profesional), module 0113 Operaciones de generacion y transferencia de energia en proceso quimico of the Tecnico en Planta Quimica (Real Decreto 178/2008) and module 0187 Generacion y recuperacion de energia of the Tecnico Superior en Quimica Industrial (Real Decreto 175/2008).
The learner is Sabela Outeiro, a newly qualified boiler operator of a fictional resins plant, through 2027, at a fire-tube steam boiler with a modulating gas burner, its gauge glass, level transmitter and low-water cut-offs, feed pumps, blowdowns, economiser and condensate return.
Four situations set the year's course: a cut-off that keeps tripping during a cold start, and how the level and its safety devices are checked (gauge glass blown down, cut-offs tested, never bypassed) and how the boiler is started (full pre-purge, low fire, the maker's warm-up curve); repeated flame failures and high boiler-water conductivity, and what is done after a lockout (the cause first and a full pre-purge before every relight) and how the boiler is blown down (on the water analysis); the restart after the August stop, and how the demand step is met (anticipated, the main valve opened slowly) and what is done with the economiser and the condensate; and a night when no water can be seen in the gauge glass, answered by cutting the burner and not feeding water to a hot boiler, and how the year's events are recorded.
Three critical errors cap the round: the low-water cut-off bypassed, the burner reset again and again without a full purge, the burner kept on and feed water opened with no visible level. KPIs: steam demand served, boiler house operating cost, energy lost a week and boiler trips and incidents. Lesson: with low water, the right sequence prevents the explosion. Spanish primary, English parity.

What participants learn
After the session, participants will be able to:
- Check the boiler level and its safety devices before firing, blowing down the gauge glass, comparing it with the transmitter and testing the low-water cut-offs without ever bypassing them
- Apply the cold-start sequence of a fire-tube boiler: a full pre-purge, ignition at low fire and the warm-up on the maker's curve with vents and drains open
- Diagnose the cause of a flame failure before any reset, and relight only after a full pre-purge
- Evaluate blowdown, load changes and heat recovery on their figures, blowing down on the water analysis, anticipating the demand step and returning the economiser and the condensate to service with a plan
- Decide to treat a low water confirmed by two indications as real: cut the burner, never feed water to a hot boiler with no visible level, isolate, cool and inspect, and record every event in the boiler log
Prerequisites
- Has seen a boiler and knows the gauge glass, cut-off, burner, pre-purge and blowdown
Who it is for
An introductory simulation that assumes no prior knowledge of the subject, designed for undergraduate courses. It also works in vocational and high-school programmes and in onboarding sessions.
How a session runs
- The instructor creates a session from the Eureka dashboard and invites the participants.
- Participants play 4 rounds. In each one they submit their decisions and the simulation calculates the results. The first round opens with: lunes 11 de enero, 5:30: el limitador que dispara y el arranque en frío.
- The simulation can be run in English, Español.
- The instructor follows each participant's progress and results from the dashboard, and uses the class results for the debrief.
