“…Another common way to measure heat flux from a flame is to use a diffusion-type Gardon Gauge. Its application in combustion is good, as shown in [4]. The design of the sensor is shown in Figure 1.…”

“…Thus, the temperature difference between the center and periphery of the disk is determined, followed by calculation of the heat flux. The Gardon Gauge has proven itself well in various fields, including measurement of heat flux in furnaces of power boilers and industrial furnaces [5], measurements of concentrated solar radiation [6], studies of heat transfer during the entry of spacecraft at hypersonic velocity into the Earth's atmosphere [4], and more.…”

“…Sensors based on hyperthermocouples [4,[7][8][9][10][11] are widely used in the study of heat transfer processes; however, they have an unavoidable drawback. The disadvantage in this case is their thickness, which is related to both sensitivity and response time.…”

Measuring the heat flux in the furnace of industrial boilers is an urgent task in the power industry. Installing the measuring instruments directly into the furnace is a laborious and complex process. It requires a complete shutdown of the boiler, which incurs economic costs. It is most efficient to use portable probes with measuring insert. The created cooled probe with a heterogeneous gradient heat flux sensor is a unique and versatile tool that allows for the configuration and control of the operation of power boilers. This article compares experimental values with calculation methods. The obtained heat flux per unit area is in good agreement with the theoretical concepts when the values are averaged. The technique used in this paper makese it possible to determine the maximum heat-stressed zones and areas with stable or unstable combustion. The main combustion zones that are typical for the flaring of any fuel are identified. This approach allows us to consider various approaches to heat transfer enhancement during the combustion of both liquid and gaseous fuels. Comparison of experimental results with the data of other authors is not quite exact due to the complexity of the experiment. The study of burners in this configuration has not previously been considered in the literature.
