Industrial Gas Fired Steam Boiler New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the boiler.

Automatic Level Control Systems | Spirax Sarco

If the demand for steam increases, the pressure in the boiler initially falls, and the control system will increase the burner firing rate. The rate of evaporation will increase to meet the increased demand. The increased rate of evaporation means that the boiler water will contain more steam bubbles and become even less dense.
