説明

<p>Hot water plays an indispensable part of our present daily life. It can be conveniently usable for everyone since the instantaneous hot water heater was developed and widespread in the market. This term, convenience, actually means that we can use hot water with required temperature and quantity on demand. In the appliance, water flow and temperature sensors are actuated and calculate the amount of energy to create the hot water with requested temperature. To realize the supply of comfortable hot water in this process, combustion must be very significant phenomenon, which can convert the enthalpy of the fuel to the heat revelation quickly. Historically hot water heater has been changed to meet the needs of end users and observes regulations to protect the environment (downsizing, weight saving, low noise and low hazardous emission). According to the modification of hot water heater, burner has also been evolved so as to attain high-intensity combustion and high stability, namely from famous conventional Bunsen type burners to the present burner referred to as low NOx emission burner. It can achieve the lean combustion in which flame is surrounded with rich flame to compensate for its weak stability. These burners can be developed mainly by many engineers' aspiration with try-and-error activity rather than calculating with the fundamental academic knowledge of combustion. Presently, more distinguished burner improvement has been so hard because many configurations has been tried already, therefore, it is expected that new breakthrough invention will be created in the field of academic combustion study and will leads to the development of new fine burner.</p>
