Boiler - Wikipedia

Boilers can be classified into the following configurations: Pot boiler or Haycock boiler/Haystack boiler: A primitive "kettle" where a fire heats a partially filled water container from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere.These could burn wood or most often, coal.

WHY IS IT IMPORTANT TO MEASURE COMBUSTION

Location (D) is typical for wall fired boilers. The preferred measurement location is downstream of the fan, preheater and primary air takeoff (as shown), but it can be made in other locations if necessitated by duct layouts. On an opposed wall-fired unit, secondary airflow measurement may also be important to balancing front and rear windboxes.
