Problems solved by technology

[0003] After nearly 3-4 years of application, domestic large-scale gas-fired hot water heating boilers have initially occupied the domestic market, but the larger gas-fired boilers are still in the stage of research and exploration and summary of operating experience, lack of relevant design experience, with the national standards for In an environment where boiler thermal efficiency and flue gas emission NOx values ​​are constantly demanding, the original gas-fired hot water boiler water circulation energy-saving system has a thermal efficiency of 95% and NOx of 120-150mg / Nm3 is far from adapting to the standards and market update speed, so , achieving higher breakthroughs in thermal efficiency, flue gas NOx index, exhaust gas temperature, etc. has become the main research direction of large gas-fired hot water heating boilers

Abstract

The invention relates to a water way circulation energy saving system of a gas-fired hot water boiler. The system comprises a furnace body, combustors, a flue, a chimney, an energy economizer and a water cooling type condenser, wherein two combustors are vertically spaced at one end of the furnace body; a smoke outlet is formed in the other end of the furnace body, and is tightly connected with the flue; an outlet of the flue is connected to the vertical chimney; the two-grade energy economizer is mounted in the flue between the furnace body and the chimney in sequence; and the water cooling type condenser is mounted on the chimney. The system is stable in operation, safe, reliable, sufficient in force, low in smoke discharge temperature and high in efficiency, reaches the smoke discharge index, and is more accordant with the market development demands.

Description

technical field [0001] The invention belongs to equipment in the field of urban central heating, in particular to a gas-fired hot water boiler water circulation energy-saving system. Background technique [0002] This equipment belongs to the main equipment in the field of large-scale central heating in cities. It is aimed at the water circulation energy-saving system of gas-fired hot water boilers used in large-scale urban heating coal-to-gas projects in the field of environmental protection and energy conservation advocated by the state. With the continuous improvement of domestic living standards, the society has gradually stricted environmental protection requirements around the living area. In the past, large-scale commercial housing and residential quarters generally used coal-fired hot water heating boilers, which caused serious dust and poisonous pollution to the surrounding living areas. Smoke pollution, cities are often shrouded in smog and dust. In order to impro...
