Description

High-efficiency segmental wall-hung furnace

technical field

The utility model relates to the technology in the field of wall-hung furnaces, in particular to a high-efficiency segmented wall-hung furnace.

Background technique

Wall-hung furnace is actually the abbreviation of gas wall-hung furnace. The term "wall-mounted furnace" is a foreign term, and its full name is: "gas wall-mounted heating furnace". The standard name in our country is: "gas wall-mounted rapid heating water heater", but it is not a gas water heater in the traditional sense, and it is essentially different from a water heater. It has various safety protection measures such as anti-freezing protection, anti-dry protection, accidental flameout protection, over-temperature protection, and water pump anti-blocking protection. An external indoor thermostat can be connected to achieve personalized temperature adjustment and energy saving. According to statistics, the use of indoor temperature controllers can save 20-28% of gas costs.

At present, ordinary 36/40KW wall-hung boilers do not use segmented burners and segmented control, and there is only one air inlet into the burner. The burner combustion during work is all combustion of 18 rows. The maximum input power of single-row combustion is 2.0-2.2KW, the minimum input power is 0.6-0.66KW, the power adjustment range of ordinary 36/40KW wall-hung boilers is 10.8-36KW, and the minimum input power of the whole machine is 10.8KW. When the cold water temperature is low in winter, the cold water temperature can reach a minimum of 1-3 degrees. This power can meet the heating and bathroom hot water requirements; The highest water inlet temperature can reach 30-35 degrees. When the water inlet temperature reaches more than 30 degrees, when the minimum input power of the whole machine is 10.8KW, the minimum water outlet temperature of the bathroom will exceed 45 degrees. When the water outlet valve of the user's bathroom is not equipped with a water mixing valve, hot water exceeding 45 degrees or even a higher outlet temperature may cause scalding for the user, thereby causing inconvenience to the user.
