Embodiment Construction

[0034] The specific technical solutions of the present invention are further described below, so that those skilled in the art can further understand the present invention, without limiting their rights.

[0035] A gas multi-fuel boiler, including a drum and a combustion chamber, a burner interface is provided on the front of the combustion chamber, and a maintenance port is provided on the side wall of the combustion chamber.

[0036] The drum includes a middle drum body, a front tube sheet and a rear tube sheet are respectively arranged at the front and rear ends of the middle drum body, and several drum inner tubes connecting the front tube sheet and the rear tube sheet are arranged in the drum. Smoke pipe, the inner smoke pipe constitutes a three-pass flue;

[0037] There is a front smoke box in front of the front tube plate, and a rear smoke outlet in the rear of the rear tube plate.

[0038] The combustion chamber includes lower left longitudinal header pipes, lower rig...

Abstract

A gas multipurpose fuel boiler comprises a boiler barrel and a combustor. The front face of the combustor is provided with a burner connector. The side wall of the combustor is provided with a maintenance opening. The boiler barrel comprises a middle boiler barrel body. The front end and the rear end of the middle boiler barrel body are provided with a front pipe plate and a rear pipe plate correspondingly. A plurality of boiler barrel inner smoke pipes are arranged in the boiler barrel, and the front pipe plate communicates with the rear pipe plate through the boiler barrel inner smoke pipes. The inner smoke pipes form a three-pass flue. The combustor is a one-pass flue. A two-pass flue is arranged between the combustor and the lower portion of the boiler barrel. The combustor and the flues are arranged optimally, and thus a pipe wall is formed through connecting fins between a water passing pipe bundle and pipes. The overall structural performance is good, production and manufacturing are convenient, the burning environment is fully improved, the smoke speed is moderate, fuel is fully burnt, hazardous substance discharge is low, and environment protection requirements are met. Maintenance is convenient, and maintenance dead angles are avoided. Any part can be maintained fast, and maintenance quality is high. High-temperature smoke discharged from the tail of the boiler can flow back to be utilized, hearth temperature is increased, and the excess air coefficient is lowered.

Description

technical field [0001] The invention relates to a boiler, in particular to a gas multi-fuel boiler. Background technique [0002] The traditional WNS gas boiler has the following characteristics: [0003] 1. The front and rear tube sheets of the backfire chamber are difficult to repair, or even impossible to repair. [0004] 2. The volume of the combustion chamber is not enough, the smoke velocity is too fast, and the emission of nitrogen oxides is high. Contents of the invention [0005] The technical problem to be solved by the present invention is to address the deficiencies of the prior art, and propose a gas-fired multi-fuel boiler with fully improved combustion environment, moderate smoke velocity, sufficient fuel combustion, low emission of harmful substances, and meeting environmental protection requirements. [0006] The technical problem to be solved by the present invention is achieved through the following technical solutions. A gas-fired multi-fuel boiler in...
