The change of layer combustion longitudinal drum boiler water level can make steam pressure unstable, even full water or lack of water accident. Therefore, in order to keep the water level fluctuating slightly near the normal water level, the boiler should supply water evenly and continuously as far as possible in order to keep the water level fluctuating slightly near the normal water level. If low water level appears, the combustion should be controlled immediately. All kinds of boilers with different structures have prescribed the minimum safe water level, which must be maintained above the minimum water level limit in the operation of the boiler. The above is manual regulation, small-sized fuel-fired gas-fired boilers are generally automatic regulation.

Users purchase their own needs or may be advantageously combined conditions are selected. On selecting the style is simpler, suitable for horizontal or vertical, provided that they meet the requirements placed layer combustion longitudinal drum boiler to boiler room.
