Abstract

The invention solves issues of increased cost and poor firing effect when method for increasing size of fire grate is adopted in honeycomb briquette boiler for producing steam. In the invention, dualfireboxes are setup at two sides of the flue. Boiler barrel is at upper end of the flue composed of convection flue and straight flue. Being setup at lower part of water-cooling fire grate inside firebox, the lower smokebox of fire grate is connected to the air distribution chamber. There is opening of flue on sidewall of lower smokebox of fire grate. Through rear backfolding flue, the straight flue is connected to the convection flue, which is connected to lower collection tank. Through front backfolding flue, the convection flue is connected to smoke tube in boiler barrel. Features are: highcombustion intensity and high thermal efficiency.

Description

technical field [0001] The invention relates to a briquette-fired boiler, in particular to a heat storage type briquette-fired steam boiler. Background technique [0002] The technology is an economical and practical clean coal technology suitable for my country's national conditions. Development and utilization can not only save energy and improve coal utilization efficiency (compared with raw coal scattered combustion, the coal saving rate of combustion boilers can reach about 15%); but also can effectively reduce environmental pollution (can reduce initial dust emission by 80%) ~90%, the blackness of flue gas is reduced to below 1 Ringelmann level, and the total sulfur fixation rate is above 50%). Under the current economic and technical conditions in our country, popularizing and using it is an effective way to solve the increasingly serious situation of air pollution in our country. Due to the smooth surface of honeycomb coal itself, it is difficult to ignite, the rea...
