Can gas boilers be started and stopped quickly?

By \"fast,\" it roughly refers to starting and stopping in about 10 minutes – is that acceptable? In my opinion, it’s quite convenient to turn gas boilers on and off. Is that so?
It’s like this for me – it depends on the steam pressure. What’s the specific fuel consumption of your gas boilers? How much natural gas is needed for one ton of steam?
This definitely won’t work. The time required for the boiler to reach the desired temperature and pressure is determined by the temperature difference between the inner and outer walls of its steam drum; this temperature difference must not exceed 50°C. It’s acceptable for a boiler that has just been shut down, but for a cold boiler, it’s necessary to follow the designed heating curve.
No, rapid start-stop operations will inevitably cause sudden cooling and heating of the boiler’s heating surfaces. The sharp changes in thermal stress on the materials of these surfaces will **reduce both the lifespan of the materials and that of the boiler itself**.
Absolutely not. Your concept is similar to the way some people understand quick-install boilers; regardless of the name given to it, the principle behind a boiler remains the same: it requires a steady heating process so that all parts of the boiler are heated evenly, thereby preventing excessive stress that could cause damage to the boiler. It is essential to start the boiler following the steps outlined in the boiler’s manual or operating instructions.
