Horizontal type single boiler barrel multipurpose fuel boiler

Abstract

A horizontal type single boiler barrel multipurpose fuel boiler comprises a boiler barrel and a combustion chamber. A combustor connector is arranged on the front surface of the combustion chamber. A maintenance opening is formed in the side wall of the combustion chamber. A front smoke box is arranged on the front portion of the boiler barrel. A back smoke outlet is formed in the back portion of the boiler barrel. The boiler barrel is internally provided with a plurality of boiler barrel inner smoke pipes communicating with the front smoke box and the back smoke outlet. The inner smoke pipes form a third return stroke flue. The combustion chamber is a first return stroke flue. A second return stroke flue is arranged between the combustion chamber and the lower portion of the boiler barrel. The front end of the second return stroke flue is sealed and communicates with the front smoke box through a left connecting bent pipe and a right connecting bent pipe. The boiler barrel, the second return stroke flue and the combustion chamber can be manufactured separately, form three components and then are assembled. The combustion chamber and the flues are optimally arranged, and a pipe wall is formed by connecting fins between water passing pipe bundles and pipes. During manufacturing, the space and the length of the combustion chamber can be arbitrarily sized, so that the combustion environment is fully improved, the smoke speed is moderate, fuel combustion is sufficient, emission of harmful substances is low, and the environmental protection requirement is met.

Description

technical field [0001] The invention relates to a boiler, in particular to a horizontal single-drum multi-fuel boiler. Background technique [0002] Traditional gas-fired boilers are very difficult to maintain, especially the front and rear tube plates of the back-fired chamber. Once cracks appear, they cannot even be repaired. [0003] Another feature of traditional gas boilers is that the combustion chamber space is too small, the volume is not enough, and the smoke velocity is too high. After the combustible gas is not fully burned, it will be discharged with the flue gas, resulting in steam output per ton or hot water heating or organic heat. The gas consumption of carrier heating is large, the cost of production or living is too high, and the emission of nitrogen oxides exceeds the standard. Contents of the invention [0004] The technical problem to be solved in the present invention is to address the deficiencies of the prior art, and propose a horizontal single-dr...
