Combi-steamer condensation hoods are widely used in modern gastronomy. They condense steam produced by the combi-steamer and also filter solid particles, moisture, grease and smells. All these factors negatively affect the staff and dishes, so efficient work of the condensation hoods becomes important. A mathematical and experimental analysis of such a device is described in this paper. First a measurement methodology was designed and measurements of air humidity, temperature and mass flow rates were performed. The measurement procedure concerned dedicated a steam generator and combi-steamer. Next a mathematical model was developed. It was based on mass and energy balances of the condensation hood. The condensate flow rate turned out to be insufficient to fulfill the energy balance while measured directly. Hence, it was calculated from heater’s power of the steam generator and the balance model was validated. The combisteamer had an unknown output, so the condensate flow rate was provided by the balance model after its validation. A preliminary diagnosis of the device was carried out as well.

The analyses and conclusions presented in the article are based on the results of qualitative panel surveys conducted among large indigent families in the years 2013 to 2014 and in 2017. The survey attempted to answer the questions of whether and to what extent the implementation of a pro-family policy in Poland in 2016 influenced the situation of large families receiving institutional social aid. On what do these families spend the payments received from the Family 500+ programme? Has their new economic situation favoured their activation or increased their ability to manage? Could the programme, in consequence, hinder or limit the intergenerational transmission of poverty? The author concludes that in fact the effects of financing large families differ from those that were intended. The programme, which was intended to be pro-natal, has acquired the nature of social aid payments. It has improved the material situation of many families, but it has not sufficiently contributed to changing ways of thinking about the children’s futures, which would contribute to limiting the processes of inheriting poverty.
