    The boiler is better able to respond to large loads as the 'low fire' position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on 'low fire', it can immediately respond by increasing the firing rate to 'high fire', for example the purge cycle can be omitted.Learn More

  • Turndown ratio in condensing water tube vs. fire tube boilers

    Improving the efficiency of our example system may take two different directions. We could use more, smaller boilers with the 5:1 turndown. We could also keep the same boiler quantity but increase the turndown. The system could use (3) boilers of 4,000,000 BTUH with the 5:1 turndown. I say 3 because the district still requires the N+1 redundancy.Learn More

  • What is needed to be increased to increase the heat

    Dec 12, 2019 · Explanation: Water velocity is required to be increased rather than gas velocities to increase the rate of heat transfer rate in the boiler, because a considerable increase in pressure is more easily produced with water than with gas. Hence, for a given output in boiler, smaller diameter tube …Learn More
