The possibility of the kinetic Alfven wave's generation in the preflare plasmas at the chromospheric heights has been proved before the phase of "preheating" in the loops and under assumption of the absence of the high-energetic particles beams in solar atmosphere. The possibility of generation of the Langmuir waves of small amplitudes in the loops with subdreicer electric fields before the flare has been proved. Langmuir turbulence, in which the former instability can transform, enables to accelerate the charged particles in preflare plasma.
