Abstract

The is about the hearth for small scale industrial boiler. It solves the insufficient burning and burnt of the gas and coal inside the hearth of the industrial boiler by avoiding the problems of the small scale industrial boiler of using diaphragm water cooling wall with relatively low temperature in the hearth that hinders the burning of fuels and affects the efficiency of the boiler. It comprises a back cove (8), an oven wall (10), and a semi circle front cove (4) which is set at the left side of the hearth with its left side lower than the right cove. After inspection, it turns out that the primary drawing off dust intensity 50% lower than GB, Zero degree Ringlemann smoke chart, output drawing off dust intensity of the smoke 11% lower than the required 80mg / m3, hearth temperature reaching 1650-1700 DEG C, improving boiler output 28%, raising heat efficiency 6.6%, reducing energy 6% and being environment friendly.

Description

technical field [0001] The present invention relates to industrial boilers. Background technique [0002] Small coal-fired chain boilers at home and abroad have been adopting oblique forward arches and slope-shaped rear arches for two hundred years, burning loose coal to pollute the environment, and various measures cannot meet environmental protection requirements. my country's boiler production enterprises and scientific research departments have invested a lot of money, manpower and financial resources in the environmental management of coal-fired industrial boilers for many years. They have developed spherical briquettes, honeycomb coal boilers and coal-fired gasification boilers, which are currently used and popularized products. The above-mentioned boilers Insufficient output, too slow temperature rise, periodic black smoke, and poor environmental protection performance are common. Therefore, heating companies and professional production units do not choose these boile...
