Problems solved by technology

Due to the widespread use of coal, electricity, and gas, the demand for straw in rural areas has decreased, and the disposal of a large amount of straw has become a serious social problem. Although it is prohibited by law, farmers in many places still burn straw in the fields, causing serious consequences such as air pollution and fires. , the problem of straw disposal has become increasingly prominent

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the boiler for the mixed combustion of straw and domestic waste of the present invention adopts a semi-outdoor arrangement. It includes a steel frame 3, a furnace chamber, a feeding device 19, a fire grate 1, and slag and ash discharge equipment 10. The furnace chamber is installed on the steel frame 3, and the canopy 4 is directly supported on the top plate of the steel frame. The furnace chamber It is composed of a furnace 2, an ember chamber 11 and three flues 12. A connecting flue 13 and a tail flue 14 are arranged behind the furnace chamber, and the furnace chamber, the connecting flue 13 and the tail flue 14 are in the shape of "冂". The slag and ash discharging equipment 10 is installed at the lower part of the fire grate 1, and the front arch 16 and the rear arch 17 are arranged at the lower part of the furnace 2 and above t...

Abstract

The invention discloses a straw and household garbage co-combustion boiler arranged in a semi-outdoor manner. The straw and household garbage co-combustion boiler comprises a steel frame, a canopy, a boiler chamber, a feed device, a fire grate and a slag and ash discharge device, and is characterized in that the boiler chamber is installed on the steel frame; the canopy is directly borne on a top plate of the steel frame; the fire grate is arranged below the boiler chamber; the slag and ash discharge device is arranged on the lower portion of the fire grate; the boiler chamber is composed of a hearth, a burnout chamber and three flues; the connection flue and the tail flue are arranged behind the boiler chamber; and the boiler chamber, the connection flue and the tail flue form an n shape. The feed device is arranged at the front of the boiler chamber; the bypass flue is installed at the position of an inlet of the tail flue; and a smoke recirculation pipeline is arranged at the position of an outlet.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a boiler which combusts straw and domestic garbage to generate steam for steam supply and power generation. Background technique [0002] Straw refers to the remaining stems and leaves of crops such as rice, wheat, and corn after they have matured and threshed. Due to the widespread use of coal, electricity, and gas, the demand for straw in rural areas has decreased, and the disposal of a large amount of straw has become a serious social problem. Although it is prohibited by law, farmers in many places still burn straw in the fields, causing serious consequences such as air pollution and fires. , the problem of straw disposal has become increasingly prominent. [0003] If the straw is crushed and used as boiler fuel, sent to the boiler and mixed with domestic waste for combustion, and the heat of incineration is used to generate steam for steam supply and power generation, this will not o...
