Multiple Steam Boiler Controls

I am gathering from the replies that using a package multiple boiler controller has had more success than letting the temperature controls contractor provide the boiler controls.

Multiple steam boiler controls.

Tekmar is a great control but. They run steam cycles which are normally 60 minutes long the length of the cycle depends on the type of radiation in the system. The mpc or mpcq platinum are steam cycling controls for single boiler or multiple boiler steam heated buildings. In multiple parallel boiler arrangements the plant master must output to each boiler s combustion controls.

Multiple boiler control mbc amb4bub amb4bub the utica boilers multiple boiler control mbc operates up to four boilers and resets the heating system water temperature based on outdoor air temperatures. This is a project for a high school and the controls have to tie into their existing bacnet temperature control system. The three elements are water flow airflow and fuel flow. In this case each boiler has its own boiler master which is an auto manual station that accepts the plant master s output applies a ratio and bias and sends the result out as the demand signal to the combustion controls.

If the demand is for space heating the controller typically determines its target temperature using outdoor reset logic. For steam boilers water flow is used to maintain the drum level.
