The fuel gas infrared radiation heating device based on the pulse combustion is simple in structure and can improve the efficiency and the safety of fuel gas radiation heating in a large space, thereby being beneficial to energy conservation and emission reduction; and moreover, the working environment of staff in the large space is improved and the comfort degree is improved as well.

Description

technical field [0001] The invention relates to a heating device, in particular to a gas infrared radiation heating device based on pulse combustion. Background technique [0002] At present, some tall industrial plants and some public buildings with a large space consume a lot of heat in the enclosure structure of cold air infiltration and intrusion of cold air. If ordinary radiators or hot air are used for heating, the thermal pressure will lead to energy waste. Seriously, and the heating effect is not good. For this kind of buildings, radiant heating is a relatively good heating type, that is, it directly provides heat to the object to be heated, rather than heating the entire large space air to achieve heating, and the energy saving effect is remarkable. Specifically, it can be divided into electricity, hot water, steam, gas and other radiation, among which gas infrared radiation heating is the most commonly used. The gas infrared radiation heating system is mainly com...

Problems solved by technology

[0003] Research has found that this conventional gas-fired infrared radiation heating has many shortcomings, such as: (1) The temperature distribution of the radiant tube is extremely uneven. 100°C, the serious unevenness of the temperature of the radiant tubes leads to uneven heating and cooling in the heating room

(2) An induced draft fan needs to be installed at the end of the radiant tube to maintain the negative pressure of the combustion chamber and the radiant tube and remove combustion products. Generally, the induced draft fan is installed indoors, which consumes a certain amount of power and the noise of the fan affects the indoor working environment

(3) Ordinary burners have insufficient combustion and low combustion efficiency. The combustion products contain carbon monoxide and nitrogen oxides, and there is a risk of carbon monoxide poisoning for staff.

[0004] The Chinese patent "Far Infrared Radiation Heating Equipment [ZL03214192.0]", the Chinese Patent "Gas Radiant Heater for High and Large Spaces [ZL200520078450.9]" and the Chinese Patent "Gas Type Infrared Radiant Heating Device [ZL03214192.0]" all elaborated a A steady-state oil / gas infrared radiation heating equipment and device based on a common burner, which is characterized in that the burner is a conventional steady-state combustion, and there is room for further improvement in combustion efficiency, and the combustion tail gas contains a large amount of incomplete combustion products such as carbon monoxide and Nitrogen oxides, in this case, there is a certain danger in using the exhaust gas of the burner for heating, and a fan is required at the end of the radiant tube, which increases power consumption on the one hand, and another fan installed indoors causes environmental noise

This is an insurmountable disadvantage of this type of steady-state combustion radiant heating
