Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] like figure 1 As shown, the garden waste incineration boiler of the present invention includes a furnace 1, a steel frame 2, a fire grate 3, a feeding system 4, a horizontal flue 5 and a tail flue 6. The furnace 1 is installed on a steel frame 2 , and the fire grate 3 is arranged below the furnace 1 . The grate 3 is an inverted chain grate, and the grate pieces are made of heat-resistant cast steel. Behind the furnace 1, a horizontal flue 5 and a tail flue 6 are arranged in sequence, and are arranged in a "Xiang" shape. A feeding system 4 is arranged at the front of the furnace 1 . A water-cooled front arch 7 is arranged under the front part of the furnace 1, and the lower edge of the outlet of the furnace 1 protrudes into the furnace to form a flame-folding angle 8. A high temperature superheater 9 is arranged above the folded flame angle 8 at the outlet of...

Abstract

The invention discloses a garden waste incineration boiler. The garden waste incineration boiler comprises a hearth, a steel frame, a fire grate, a feeding system, a horizontal flue and a tail flue. The back of the hearth is sequentially provided with the horizontal flue and the tail flue which are arranged to be in an n shape. An ash hopper and a backdraft pipe are arranged on the lower portion of the horizontal flue. The fire grate is a reverse chain fire grate. Baffles are arranged on the upper portion of the last row of tube bundles of a middle-temperature superheater, and clearances are reserved among the baffles. The feeding system is arranged in front of the hearth and comprises a garden waste bin, a standby stock bin, conveying devices, air supplying devices and a feeding hopper. The feeding system can be uniformly arranged to be in a multi-line parallel mode according to the width of the fire grate. The feeding hopper is divided into an upper layer and a lower layer, the upper layer is a garden waste hopper body, the lower layer is a standby fuel hopper body, and the independent air supplying devices are arranged on the garden waste hopper body and the standby fuel hopper body correspondingly. According to the garden waste incineration boiler, garden waste can be efficiently processed, and the feeding system can be flexibly and conveniently adjusted according to the change conditions of the garden waste so that continuous operation of the boiler can be ensured.

Description

technical field [0001] The invention relates to a garden waste incineration boiler which burns garden waste and generates steam for steam supply and power generation. Background technique [0002] Garden waste, also known as garden waste, mainly refers to the dead branches, fallen leaves, withered flowers, tree and shrub pruning and other plant residues produced by the natural fall of garden plants or artificial pruning. With the continuous acceleration of urbanization in my country and the improvement of human settlements, the total amount of urban gardens and green spaces has continued to grow steadily, but the waste generated by greening has also continued to increase. Nowadays, energy is scarce and prices remain high. As a renewable energy source, garden waste can not only be used to improve economic efficiency; at the same time, compared with other urban waste, garden waste has less pollution and does not contain toxic substances such as heavy metals. Harmful substance...
