| (54) | A method for regulating the combustion process in solid fuel central heating boilers |
| (57) The method for regulating the combustion processes in solid fuel central heating
boilers, whereby the energy parameters of the combustion are set at the level relevant
for the type of solid fuel and the type of boiler and the combustion process is regulated
by changing the amount of solid fuel and air introduced on the basis of temperature
measurements, consists in that the temperature tmg of the heating medium is measured as well as temperature tsp of the combustion product in at least one place in the bottom layer of the solid
fuel aftercombustion zone or additionally temperature tp of the combustion product in the ash zone is measured and then the temperature tmg of the heating medium is compared with the preset temperature, and that the amount
of primary air pp introduced into the process is measured or additionally also the amount of secondary
air pw and then the amount of primary air pp or the total amount of primary pp and secondary air pw is compared with the preset amount and subsequently, based on the algorithm appropriate
for the given boiler, it is converted into an impulse for adjusting the settings of
solid fuel and/or air inflow, whereby the algorithm takes into account a relevant
deviation of the primary air Δpp or primary and secondary air Δppw and the known deviation of temperature Δtmg of the heating medium and temperature tsp of the combustion product or additionally also the corresponding in time temperature
tp of the combustion product in the ash zone.
