Mechanical ChCR /ЧЦР/ stokers with the forward chain motion rippled gate are designed for burning of black and brown coals, screened anthracites of the АС (AS) and АМ (АМ) grades under stationary steam boilers with heat productivity up to 50 MW.

They can be used in process units with a sufficient capacity of furnace chambers. Stokers ChCR /ЧЦР/ are not recommended for anthracites of the grades ASSh and ARSh /АСШ и АРШ/ combustion.
