Description

Premix closed module gas boiler
Technical field
The present invention relates to a kind of gas fired-boiler, particularly relate to a kind of multiple-unit module gas boiler.
Background technology
Existing modular boiler adopts air suspended type semi-close burning mode room mostly, and because combustion chamber belongs to semi-open structure, the waste gas of the generation of burn incompletely can fill the air boiler room, can set off an explosion or the major accident such as personnel are poisoning when concentration acquires a certain degree; Burner transmits amount of heat by radiation and convection type around body of heater simultaneously, causes energy waste, reduces the thermal efficiency of boiler;
In conventional module formula boiler, calandria burner is generally single-cylinder type structure, and this structure easily causes tempering, accidents caused, and because air-flow is stable not during burning, causes fired state to fluctuate large, makes burning insufficient, reduces fuel availability;
Conventional modules boiler heat-exchanging device many employings carbon steel or cast-iron structure, belong to volume circulation type heat exchange, and the boiler water capacity of this structure is large, and volume is heavy, and time standby, in-fighting is comparatively large, and take up an area, load-bearing, give and to install and use causes extreme difficulties.
Summary of the invention
For overcoming the lower problem of the gas fired-boiler thermal efficiency that above-mentioned technological deficiency causes, the invention provides a kind of closed module gas boiler, by improving the ignition system of boiler, integrate and optimize the inner configuration such as the burner of existing gas fired-boiler and heat-exchange system, the intelligence control system of supporting boiler applications, to reduce boiler in-fighting, improve automaticity and the thermal efficiency of boiler.
