Firewood straw direct-combustion boiler and combustion process thereof

Abstract

The invention belongs to the technical field of boilers and boiler burning and in particular discloses a firewood straw direct-combustion boiler and a combustion process thereof, wherein the boiler comprises a boiler body, a dust collecting chamber, and a thermolysis combustion chamber with a water jacket, a water cooling grate is arranged at the lower end of the thermolysis combustion chamber, a reinforcing combustion chamber is arranged below the water cooling grate and communicated with a boiler gas distributing chamber which is communicated with a boiler heat exchange chamber, the top end of the boiler heat exchange chamber is connected with a chimney communicated with the atmosphere, and the water jacket and the water cooling grate are respectively communicated with a water tank of the boiler heat exchange chamber at one side of the thermolysis combustion chamber. In such technical proposal, the combustion process of the boiler is combined with the structure thereof, thereby realizing the direct combustion of firewood straws, solving the problems of low heat value of the firewood straws and low heat intensity, providing a practical and feasible approach capable of leading to the full use of the firewood straw energy for the firewood straw treatment during the agricultural production and also reducing the environment pollution caused by burning the firewood straws.

Description

technical field [0001] The invention belongs to the technical field of boilers and boiler combustion, in particular to a firewood straw direct-fired boiler and a combustion process thereof. Background technique [0002] With the development of the economy, mechanized farming and harvesting methods are adopted in rural areas. In order to protect the environment, the policy of prohibiting the burning of firewood and straw has been introduced. Since the treatment of firewood and straw cannot be solved well, the problem of prohibiting burning has not been fundamentally solved. This is faced with the problem of finding a better outlet for firewood straw. With the rise of coal prices, the economic burden of heating in winter in rural areas and towns and other relatively backward areas is increasing, and even most rural areas have difficulty in heating. However, firewood straw is used as fuel to burn directly for heating, and the calorific value of firewood straw is low. , the hea...

AI Technical Summary

Problems solved by technology

The direct-fired boiler realizes the direct combustion of firewood straw, solves the problem of low calorific value and low heat intensity of firewood straw, and provides a feasible and fully utilized energy source for firewood straw treatment in agricultural production. It also reduces the environmental pollution caused by burning firewood straw
