Cabinet type biomass hot blast stove

Abstract

A cabinet type biomass hot blast stove comprises a cabinet. A fuel barrel and multiple layers of heat exchange rotary liners are respectively arranged on a grate above a burning chamber in the cabinet. The lower portion of the outer wall of the fuel barrel is provided with a secondary air box tightly connected with the fuel barrel. The air inlet of the secondary air box is connected to a secondary air tube. The outer wall of the fuel barrel is provided with a plurality of secondary air holes corresponding to the secondary air box. A gas exhaust tube penetrates out of the cabinet, the penetrating end of the gas exhaust tube is provided with a jet pipe in a penetrating manner from exterior to interior, and the lower end of the jet pipe is connected to a jet fan. Each heat exchange rotary liner between the bottom layer of the heat exchange rotary liner and the top layer of the heat exchange rotary liner is connected to one gas inlet channel pipe and one gas outlet channel pipe which are respectively arranged on two sides corresponding to the heat exchange rotary liner. According to the cabinet type biomass hot blast stove, the multi-point air-distribution counter-burning technology is adopted, the stove is capable of burning completely, gas is eliminated, and environment is protected; meanwhile, since the rotary liner heat exchange technology is adopted, the hot blast stove air flow amount is maximized, and gas exhausting temperature of the hot blast stove is decreased greatly.

Description

technical field [0001] The invention relates to a stove, in particular to a cabinet-type biomass hot blast stove with a multi-layer rotary heat exchange furnace. Background technique [0002] At present, the following problems generally exist in various small stoves: 1. It can only burn coal, and it is difficult to use many fuels with low calorific value, which limits the source of fuel. Garbage; 2. Since the hot blast stove only has a primary air inlet, the fuel in the furnace cannot be fully burned during use, which not only causes a lot of black smoke, but also has low thermal efficiency; 3. The flue gas flow is too short and the flue gas resistance is caused by increasing the flue gas flow The problem of too large, the flue gas rises too fast, and the heat exchange effect is not good; 4. In the past, the smoke exhaust fan was working at a high temperature, which had the disadvantages of high cost, high maintenance rate, and high damage rate. Contents of the invention ...

The flue gas flow is too short and the flue gas resistance is caused by increasing the flue gas flow The problem of too large, the flue gas rises too fast, and the heat exchange effect is not good; 4. The previous smoke exhaust fan is working at high temperature, which has the disadvantages of high cost, high maintenance rate and high damage rate
