A model is presented explaining changes in cometary brightness during an outburst at large heliocentric distances. It is shown that a combination of the following effects can explain the main characteristics of outburst at large heliocentric distances: the specific exothermic processes in cometary nucleus (as the HCN polymerisation and the crystallization of the water amorphous ice, connected with the ejection of the large quantities of dust) and the sublimation of CO or CO2 from the comet's nucleus. The obtained results are in good agreement with observations.
