Low mass X-ray binaries are binary star systems, consisting of a late type main sequence star and a compact object. This class of objects is known to emit regular X-ray flares on the time scales of years to decades. In our work we present an energy balance stage model for such a behavior and apply it to the case of IGR J17498-2921 2023 Apr. flare. We present the results of our analysis of NUSTAR and Spektr-RG/ART-XC observations of the source. Each of the satellites detected 2 type I X-ray bursts from the source, which let us determine burst recurrence period during flare activity, estimate its possible value during the quiescence period and gave a hint on accreted material composition. Comparatively low burst duration witnesses of a H poor accreted material and so a highly evolved optical companion star. Burst spectra were well fitted with absorbed thermal radiation model, while persistent radiation spectra also required a hot corona, accretion disk and reflection of coronal radiation from the disk components to be added to the model.
