Abstract

The invention relates to a large gas-fired hot water boiler. The large gas-fired hot water boiler comprises a boiler body, combustors, a flue, a chimney, economizers, a water-cooling-type condenser, a second-stage air-type condenser and a first-stage air-type condenser, wherein one end of the boiler body is provided with the two combustors which are vertically arranged at an interval; the other end of the boiler body is provided with a smoke outlet and is connected with the flue in a sealed manner; the outlet of the flue is connected with the vertical chimney; two stages of economizers are sequentially arranged in the flue between the boiler body and the chimney; the water-cooling-type condenser, the second-stage air-type condenser and the first-stage air-type condenser are sequentially arranged on the chimney from bottom to top; and smoke in the boiler body is exhausted from the boiler body, sequentially passes through the two stages of economizers, the water-cooling-type condenser, the second-stage air-type condenser and the first-stage air-type condenser, and is finally exhausted through the upper end of the chimney. The large gas-fired hot water boiler has the advantages that the operation is stable; safety and reliability are ensured; the output is sufficient; the exhaust gas temperature is low; the efficiency is high; the smoke emission index meets the requirement; and the market development requirement is better met.

Description

technical field

[0001] The invention belongs to equipment in the field of urban central heating, in particular to a large-scale gas-fired hot water boiler. 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 large-scale 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 improve the quality of life of urban people, the city began to...
