Problems solved by technology

[0005] In addition, the angle between the drying section grate, combustion section grate and burnout section of the existing incinerator and the horizontal line is 26°, 24° or 0°. If the angle is too large to cause garbage The residence time in the furnace is short, and when the angle is designed to be 0°, the garbage rolls unevenly, and the garbage cannot fall freely, and there are problems such as incomplete combustion and high mechanical incomplete combustion loss. The slag thermal ignition loss rate of the three included angle designs is about 95%

Abstract

The invention discloses an incineration boiler integrated system for efficiently treating high-calorific-value garbage, and relates to the technical field of garbage incineration equipment. The systemcomprises a fire grate frame, the fire grate frame is provided with a water-cooling hearth, a fire grate arranged on the fire grate frame is arranged in the water-cooling hearth, the upper end of thewater-cooling hearth is provided with a smoke outlet, a garbage inlet is arranged at the front end of the water-cooling hearth, a slag outlet is arranged at the rear end of the water-cooling hearth,and the smoke outlet of the water-cooling hearth is connected with a flue set. The fire grate frame is provided with the water-cooling hearth so that the high-calorific-value household garbage can betreated, a scheme is provided for the treatment of the high-calorific-value garbage at present, the heat of the garbage can be utilized to the maximum, and the heat efficiency is high.

Description

technical field [0001] The invention relates to the technical field of garbage incineration equipment, in particular to an integrated system of incineration boilers for efficiently treating high calorific value garbage. Background technique [0002] With the development of the economy, the continuous improvement of people's living standards, and the continuous enhancement of waste classification awareness, more and more regions have a rapid rise in the calorific value of waste, especially in some developed regions and countries, which leads to the original low calorific value and high ash content. The high-moisture incineration boiler system is difficult to operate economically and stably, such as severe coking and corrosion on the heating surface, frequent tube bursts, etc. [0003] Moreover, with the changes in waste subsidy policies in different regions and the high requirements for environmental protection, the investment cost of the project has increased. How to select ...
