Power generating and heating dual-purpose boiler capable of adopting solid fuel and fuel gas

Abstract

The invention discloses a power generating and heating dual-purpose boiler capable of adopting solid fuel and fuel gas. The power generating and heating dual-purpose boiler comprises a heating container, a boiler furnace, a boiler body, a boiler cover, a boiler grate, a heating coiled pipe, fuel gas pipelines, fuel gas holes, a fuel opening, an air door and a chimney. The fuel opening and the airdoor are formed on the wall of the boiler body, the fuel opening is formed in the upper portion of the boiler grate, and the air door is arranged on the lower portion of the boiler grate; the boiler cover covers the upper end of the boiler body, and the heating container is arranged on the boiler cover, and the heating coiled pipe is arranged on the lower portion of the heating container and stretches into the boiler body; the boiler grate is arranged on the lower portion of the boiler body; the boiler furnace is arranged at the center of the heating coiled pipe; spiral air pipes stretch to the upper portion of the boiler grate in an obliquely-upward mode along the wall of the boiler body; the fuel gas pipelines are arranged on the boiler grate, and fuel gas holes are formed in the fuel gas pipelines; a dust groove is formed in the inner wall of the boiler body, the chimney is arranged on the upper portion of the dust groove, and the lower portion of the dust groove is matched with theboiler grate; the heating container comprises a water storage tank, a water inlet and a water outlet, the water outlet is formed in the upper portion of the water storage tank, and the lower end of the heating coiled pipe is connected with the water inlet. The power generating and heating dual-purpose boiler is suitable for heating and can be also used as a power generating boiler.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to a dual-purpose boiler for power generation and heating that can use solid fuel and gas. Background technique [0002] In response to the country's call to improve the living standards of the rural population, local governments are vigorously developing rural residential heating work, and rural bungalows are generally far apart, with long pipe networks and large heat loss; residential buildings are generally not energy-saving buildings and have high heat loads. It's a bit like a villa area. Some heating companies are unwilling to invest in boiler rooms for heating in villa areas. The initial investment and operating costs are higher than those of residential areas. At present, there are two schemes of independent heating for each household or centralized heating for a village. At the same time, the problem of stacking waste such as straw and wood produced in rural produc...

Problems solved by technology

[0003] In addition, most of the power generation boilers in the prior art are gas-fired or coal-fired boilers. For the use of other fuels, there are also problems of low thermal efficiency and excessive emission pollution. Moreover, there is a need for a high thermal efficiency and good environmental performance that is also applicable to other fuels. low emission boiler
