Problems solved by technology

[0004] 1. The economizer is outside the boiler, with complex and loose structure
[0005] 2. The heating surface in the cylinder is the furnace and two sets of convection tubes with three returns, and the process is more complicated
This configuration makes the overall structure of the boiler relatively loose

Abstract

The present invention relates to heating apparatus technology, and especially a kind of integrated two return condensation type oil burning and gas burning steam boiler with energy economizer. The steam boiler includes a barrel, a furnace, a regenerative combustor, a convection tube, a front smoke box, a coiler energy economizer and a combustor. The present invention has high heat efficiency, low smoke exhaust temperature and simple and compact structure.

Description

Technical field: [0001] The invention relates to a boiler. Specifically, it relates to an integrated two-pass condensing fuel and gas steam boiler with an economizer. It belongs to the technical field of heating equipment. Background technique: [0002] A boiler is a heating device. It uses coal, oil or gas as fuel, and generates heat through combustion to produce steam. The flue gas and slag produced by coal-based fuels will pollute the environment and endanger people's health, and the combustion technology and flue gas treatment are more complicated. Oil and gas fuels are easy to transport and use. Under good combustion conditions, they basically do not produce environmental pollution and have high calorific value. In recent years, due to the small size, high degree of automation, and convenient installation of oil-fired gas-fired boilers, they can be used very conveniently and flexibly under various heat media. [0003] The most typical furnace type of the previous o...
