技术领域technical field
本实用新型涉及一种燃气燃烧器，尤其是一种生物质燃气燃烧器。The utility model relates to a gas burner, in particular to a biomass gas burner.
背景技术Background technique
生物质煤气是一种低热值的气体，其热值一般在3MJ/m3左右。这种煤气的可燃组分由CO、CnHm、H2、CH4组成。生物质燃气的热值、可燃组分随生物质的种类、状态、含水率、气化炉的类型的不同而变化。要保证生物质煤气的充分、稳定的燃烧，燃烧器必需具备较好的性能。首先，燃烧器应具有较大的调节比，以适应不同的热负荷。其次，燃烧器在结构设计上应能够使生物质燃气与空气实现均匀的混合，为充分燃烧奠定基础，再者，燃烧器应具有较高的燃烧稳定性，这是低热值燃气燃烧的难点，否则就容易发生脱火与回火现象。目前，市场上还没有能满足上述要求的燃用低热值的燃烧器。Biomass gas is a gas with low calorific value, and its calorific value is generally around 3MJ/m 3 . The combustible components of this gas consist of CO, C n H m , H 2 , CH 4 . The calorific value and combustible components of biomass gas vary with the type, state, moisture content and type of gasifier of biomass. To ensure sufficient and stable combustion of biomass gas, the burner must have good performance. First of all, the burner should have a large turndown ratio to adapt to different heat loads. Secondly, the structural design of the burner should be able to achieve uniform mixing of biomass gas and air, laying the foundation for full combustion. Furthermore, the burner should have high combustion stability, which is a difficulty in the combustion of low calorific value gas. Otherwise, it will be prone to fire off and tempering. At present, there is no burner with low calorific value that can meet the above requirements on the market.
实用新型内容Utility model content
本实用新型的目的是提供一种生物质燃气与空气能够均匀混合、燃烧稳定的生物质燃气燃烧器。The purpose of the utility model is to provide a biomass gas burner which can mix uniformly with air and burn stably.
本实用新型的技术方案是：一种生物质燃气燃烧器，由控制电路、燃气装置和启动装置组成；燃气装置包括燃气管、燃气喷管和过滤器，启动装置包括油点火装置、风机、空气管和燃烧混合管，电磁阀设在过滤器和燃气喷管之间，其特征是：在过滤器和燃气喷管之间设有电磁阀，电磁阀与控制电路连接，在空气管内设有与控制电路连接的光传感器和热传感器，燃气装置的燃气喷管置于空气装置的燃烧混合管内且在燃气喷管的管壁上设有径向喷孔。The technical scheme of the utility model is: a biomass gas burner, which is composed of a control circuit, a gas device and a starting device; the gas device includes a gas pipe, a gas nozzle and a filter, and the starting device includes an oil ignition device, a fan, an air pipe and the combustion mixing pipe, the solenoid valve is set between the filter and the gas nozzle, and it is characterized in that: there is a solenoid valve between the filter and the gas nozzle, the solenoid valve is connected with the control circuit, and there is a connection with the air pipe in the air pipe. The optical sensor and thermal sensor connected to the control circuit, the gas nozzle of the gas device is placed in the combustion mixing pipe of the air device and radial nozzle holes are arranged on the tube wall of the gas nozzle.
本实用新型的特点：Features of the utility model:
1、克服了生物质燃气中存在高浓度焦油的难题。本燃烧器的燃烧方式采用预混燃烧。其燃烧效果的好坏与燃气与空气的均匀程度有直接的关系，为了强化燃气与空气的混合，采用了燃气和空气的流动方向垂直交叉流动结构的设计方案，燃气从布设在燃气管道上的进气喷孔中径向均匀喷射与沿轴向流动的空气进行混合，充分混合后的混合气体进入燃烧室燃烧将生物质燃气中的焦油燃烧掉，这样就克服了生物质燃气中的焦油对电控装置元件影响的难题。1. Overcome the problem of high concentration of tar in biomass gas. The combustion method of this burner adopts premixed combustion. The quality of its combustion effect is directly related to the uniformity of gas and air. In order to strengthen the mixing of gas and air, the design scheme of the flow direction of gas and air is vertically crossed. The radial uniform injection in the air inlet nozzle is mixed with the air flowing in the axial direction, and the fully mixed mixed gas enters the combustion chamber to burn the tar in the biomass gas, thus overcoming the tar in the biomass gas. Difficulty affecting electronic control device components.
2、由于生物质燃气热值较低，采用直接点火(电打火或脉冲点火)存在一定难度，所以本燃烧器采用油点火器同燃气管道上的进气喷孔中喷出的高浓度生物质燃气相结合的方式进行点火，可以顺利地将低热值的生物质燃气点燃。2. Due to the low calorific value of biomass gas, it is difficult to use direct ignition (electric ignition or pulse ignition), so this burner uses an oil igniter and high-concentration biomass sprayed from the intake nozzle hole on the gas pipeline. Combination of biomass and gas for ignition can successfully ignite biomass gas with low calorific value.

具体实施方式Detailed ways
本实用新型结构的结构如图1所示：由控制电路5、燃气装置和启动装置组成；燃气装置包括燃气管1、可调控阀门2、燃气喷管6和过滤器3，启动装置包括油点火装置9、风机10、空气管12和燃烧混合管8，在过滤器3和燃气喷管6之间设有电磁阀4，电磁阀4与控制电路5连接，在空气管12内设有与控制电路连接的光、热传感器11，燃气装置的燃气喷管6置于空气装置的燃烧混合管8内且在燃气喷管的管壁上设有径向喷孔7。The structure of the utility model structure is shown in Figure 1: it is composed of a control circuit 5, a gas device and a starting device; the gas device includes a gas pipe 1, an adjustable valve 2, a gas nozzle 6 and a filter 3, and the starting device includes an oil ignition Device 9,
本实用新型的工作原理：当生物质进入燃烧机时，经过滤器3、电磁阀4后燃气从径向进入燃烧混合管8内，混合管内有风机提供流动空气，把燃气经混合后由点火器点燃，喷出火苗到燃烧室内。本装置采用油燃料点火器点火，把混合器燃气点燃，主要因为生物质燃气热值较低，直接点火存在一定难度，所以采用油燃方式，点火可靠，启动时采用光传感器11控制把电磁阀4打开，燃气进入燃烧器，启动油点火系统将燃起点燃，把气点着后自动停止，这时燃气燃烧启动工作。当停止燃烧时，采用热传感器，由烤房温度传感电路控制，燃烧器自动停止。The working principle of the utility model: when the biomass enters the burner, the gas enters the combustion mixing tube 8 from the radial direction after passing through the filter 3 and the solenoid valve 4. There is a fan in the mixing tube to provide flowing air, and the gas is mixed by the igniter. Ignite and spray flames into the combustion chamber. This device uses an oil-fuel igniter to ignite and ignites the gas in the mixer. The main reason is that the biomass gas has a low calorific value and it is difficult to ignite directly. Therefore, the oil-fueled method is used, and the ignition is reliable. When starting, the optical sensor 11 is used to control the solenoid valve. 4 Turn on, the gas enters the burner, the oil ignition system will be ignited and ignited, and it will automatically stop after the gas is ignited, and the gas combustion will start to work at this time. When the burning is stopped, the thermal sensor is used, controlled by the temperature sensing circuit of the oven, and the burner stops automatically.
