Description
Technical field
The present invention relates to technical field of water heaters, specially a kind of gas heater of equal flame burning.
Background technique
Gas heater refers to using combustion gas as fuel, is transferred heat to by way of combustion heating and flow through exchange
To reach a kind of burner for preparing hot water purpose in the cold water of device；
Gas heater usually makes whole burner ignitions in the case where the big inflow temperature of water flow is low, we will
This state is known as " standard-sized sheet combustion state ", and in the case where the small inflow temperature of water flow is high, gas heater does not need to beat
Open whole burners, it is only necessary to which a part of burner kindling can reach user's set temperature demand, we claim this state
For " half-open combustion state ".In most cases, especially summer, gas heater work in half-open combustion state.
But traditional gas heater is when half-open combustion state works, for left and right sectional combustion mode (_ such as the following figure
3).Start gas heater after, only light left or right side burner, the burner position of working condition compares concentration, when
When combustion heating, since heating location compares concentration, and the heat exchanger unilateral side being heated then be heated for a long time (no matter it is half-open or
Standard-sized sheet combustion state, heated), heat exchanger service life is short, and the ability of absorption per unit area heat is limited, therefore not
Absorbed heat is discharged and largely wastes, and also just equivalent and gas energy is largely wasted, to solve the above problems, because
This proposes a kind of gas heater of equal flame burning.
Summary of the invention
The purpose of the present invention is to provide a kind of gas heaters of equal flame burning, have and are convenient for Combustion Process Control tune
Section, heating speed is fast, the small advantage of heat-energy losses, solves in the prior art that water heater service life is short, heat-energy losses it is big and
The problem of wasting combustion gas largely.
To achieve the above object, the invention provides the following technical scheme: a kind of gas heater of equal flame burning, including shell
Body, equal flame combustion system, control system；

Compared with prior art, beneficial effects of the present invention are as follows:
Flame combustion gas water heater, the temperature holding that family can be used to be arranged by gas ratio valve are stablized for this, gas shutoff valve
The work of each burner is adjusted by gas distributor and gas shutoff valve cooperating in the shutdown of control input combustion gas,
Each burner is successively adjacent arranged in parallel, combustion state can be adjusted to standard-sized sheet burning shape according to use environment and user demand
State or half-open combustion state, combustion gas pass through the blast tube of S-shaped in gas distributor, using water heater no matter in standard-sized sheet burning shape
State may be implemented uniformly to heat heat exchanger, can avoid in half-open combustion state still in half-open combustion state
When, only heat exchanger unilateral side is heated, keeps heat exchanger unilateral side impaired, it is short so as to cause water heater service life；And
The ability for avoiding heat exchanger absorption per unit area heat is limited, is discharged and largely wastes so that heat is not absorbed, etc.
It is largely wasted with gas energy；For flame combustion gas water heater when half-open position works, oxidizer is from adjacent flat for this
Enter burner head between the burner of row arrangement and participate in burning, keeps fuel gas buring more abundant, the thermal efficiency is higher.This flame burning
Gas heater, half-open combustion state to standard-sized sheet combustion state convert when, flame transfer mode is by traditional unidirectional delivery
It is changed to bi-directional, burning has higher success rate, and combustion process is more convenient for controlling, and heating speed is fast.
