Novel heating furnace special for boiler

Abstract

The invention discloses a novel heating furnace special for a boiler. The novel heating furnace special for the boiler comprises a heating furnace body; the heating furnace body is arranged under a boiler and divided into upper and lower layers, wherein a heat absorption, heat accumulation and radiation chamber is arranged at the upper layer, while a gas chamber is arranged at the lower layer; refractory balls or refractory checker bricks are orderly stacked in the heat absorption, heat accumulation and radiation chamber according to designed dimension standards to guarantee that the gas passes upwards to be combusted and to ensure heat accumulation; the gas chamber is built by use of refractory hollow bricks or refractory bricks to allow the gas to pass smoothly; a gas combustion and ignition device is arranged on the furnace wall of the lower end of the gas chamber. The special novel heating furnace for the boiler integrates high efficiency and environmental protection and adopts gas as an energy source, the tail gas is low in sulfur, contains micro dust and has no pollution, the heating temperature can be up to 1300 DEG C, and since the refractory balls or refractory checker bricks are orderly stacked in the heat absorption, heat accumulation and radiation chamber at the upper layer of the heating furnace, heat accumulation is ensured, delayed efficiency, high efficiency and energy conservation are achieved; meanwhile, the waste heat energy utilization value of the waste gas is high, and the novel heating furnace is simple in operation, safe and convenient, and low-carbon and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of boiler heating equipment, and in particular relates to a special heating furnace for boilers. Background technique [0002] In the economy and society, boilers are used for power generation, heating, and heating, and their superiority has been increasingly proven, and it is difficult to replace them with other methods. The driving energy of the current boiler (except hydraulic power) still uses coal, firewood, biomass, oil and various gases. From the perspective of economic value, coal is the most economically used, but no matter what kind of energy is used as fuel energy, its value is difficult to meet the economic and social requirements, and the pollution is serious, which endangers human beings. Although today's science and technology are changing with each passing day, there is still Fail to have any cheap and easy way to obtain high efficiency and energy saving and solve serious pollution.
