The invention provides brewing equipment with a combustion chamber and an application method thereof. The brewing equipment comprises a brewing tank and external equipment, wherein the external equipment is communicated with the brewing tank and the outer side, so as to circulate materials and cold and hot water; the brewing tank comprises a saccharifying and filtering tank and a heating tank; theheating tank and the saccharifying and filtering tank are communicated with the external equipment; the saccharifying and filtering tank is arranged above the heating tank; a separation plate is arranged between the saccharifying and filtering tank and the heating tank; the temperature of the hot water generated by the heating tank is adjusted by the cold water and then the water enters the saccharifying and filtering tank; the saccharifying and filtering tank is provided with a saccharifying cavity, a filtrate cavity and a filtering sieve plate; the filtering sieve plate is arranged betweenthe saccharifying cavity and the filtrate cavity; the filtrate cavity is formed by the filtering sieve plate and the separation plate. Therefore, an integrated design of the brewing tank is adopted toreplace a saccharifying tank, a filtering tank, a hot water tank and a heat medium system, which are separated, and high integration of the system is realized; the problem that fields and funds are limited is solved.
