Problems solved by technology

The disadvantages of this structure are: 1. Each gas module needs a small fan, and each small fan needs to be equipped with a wind pressure switch. There are many electrical components and fault points, which have a great impact on the stability of the system; 2. The small fan needs to occupy a certain space. On the one hand, it squeezes the

Abstract

The invention provides a high-efficiency centralized air inducing and distributing system for a modular furnace. A three-phase fan is arranged above a furnace shell. A condensation cavity and a smoke discharging cavity are formed in a smoke discharging pipe. An air inlet is formed in the upper end of the condensation cavity. Air outlets are formed in the lower end of the condensation cavity and the lower end of the smoke discharging cavity correspondingly. An air supplement passageway is formed by the air inlet, the condensation cavity and the air outlets. Condensation pipes are arranged on the condensation cavity. The bottoms of the condensation pipes communicate with the smoke discharging cavity. A smoke inlet is formed in the upper end of the smoke discharging cavity. An energy smoke passageway is formed by the smoke inlet, the smoke discharging cavity, the condensation pipes and the three-phase fan. Through one three-phase fan, the stability of the system is improved; through a transverse expansion condensation waste heat recovering device, the smoke discharging temperature is decreased, and the heat efficiency is improved; the air uniformizing effect of a main heat exchanger and the waste heat recovering device is improved, the heat efficiency is further improved, the air resistance is reduced, the loading capacity of an induced draft fan is reduced, and electric energy is saved; and the air supply of a fuel gas module is precisely controlled, the peroxide coefficient is strictly controlled, and the optimal combustion is achieved.

Description

technical field [0001] The invention relates to the field of gas boilers, in particular to a high-efficiency centralized air induction and air distribution system for modular furnaces. Background technique [0002] Condensing gas modular furnace is a new type of central heating equipment, which has remarkable energy-saving and environmental protection effects. It is widely used in large-scale places such as factories, office buildings, commercial and residential quarters, hospitals, supermarkets, hotels, bathing centers, swimming pools, etc. Hot water. [0003] Several gas modules are installed in the gas module furnace, and the gas modules mainly use natural gas or coal gas as fuel. According to the combustion formula of the fuel (for example in natural gas CH 4 +2O 2 =CO 2 +2H 2 O) and the ratio of air and oxygen: When the gas module is working, more than 10 times the air supply is needed to provide the oxygen required for the fuel to fully burn. Fuel and air are mix...
