<section id="historical-evolution">
<h2>Historical Evolution</h2>
<p>Historically, flame detection began with simple visual observation and progressed into sophisticated automated systems. The earliest forms utilized visual cues like the naked eye or simple mirrors to identify flame presence. As industries grew, the need for more reliable methods became evident.</p>
<h3>Optical Flame Detectors</h3>
<p>Optical flame detectors emerged using UV (ultraviolet) and IR (infrared) sensors. Their development marked a significant milestone in the industry, providing faster and more accurate responses to flame presence by analyzing specific spectral lines.</p>
<h3>Combustion Gas Detectors</h3>
<p>The development of sensor-based detectors, such as ionization and photoelectric smoke detectors, represented a further advancement. These technologies helped in detecting the chemical byproducts of combustion separately from detecting the flame itself.</p>

<h2>FAQs</h2>
<div class="faq-question">
<strong>Q: What are the basic principles behind flame detection technology?</strong>
<div class="faq-answer">
<p>Flame detection systems typically use sensors to detect either the infrared (IR) or ultraviolet (UV) radiation emitted by flames. More advanced systems may incorporate a combination of IR and UV detection along with visible spectrum sensors and data analysis using AI and machine learning to improve accuracy and reduce false alarms.</p>

<div class="faq-question">
<strong>Q: How do temperature fluctuations affect flame detection systems?</strong>
<div class="faq-answer">
<p>Temperature fluctuations can sometimes cause false alarms, as some sensors may pick up other heat sources as potential flames. Modern systems often incorporate self-diagnostic features and calibration to distinguish between actual flames and non-fire heat sources, thereby minimizing such incidences.</p>
