In the heating, heating system, industrial steam system, hot and cold water system in the high temperature boiler is more common, due to the internal medium temperature and the outside of the high temperature and low temperature ambient temperature is different from the impact of a large amount of heat loss, a waste of energy, while the heat transferred to the outside world, will cause the workshop environment temperature rise, resulting in scalding of the operator, but also affects the operation of other equipment.
The heat loss of the boiler mainly consists of two major aspects: one is the problem of heat loss of the boiler equipment; the other is the problem of heat loss of other ancillary equipment or ducts in the boiler room. Other equipment heat loss is small, small and medium-sized boiler combustion air taken from the boiler inside, the cooling system can also increase the air temperature inside the boiler. At the same time, the boiler auxiliary equipment and piping heat dissipation can also play a role in assisting heating.
Generally speaking, the boiler insulation layer consists of three layers, respectively, the inner (surface) layer, insulation layer and outer (surface) layer, each layer has its specific role.
First, the role of boiler insulation
Boiler insulation is to reduce the surface temperature of the boiler, reduce heat loss and energy saving and set up. Specifically, the boiler insulation layer has the following roles:
1. reduce heat loss, improve boiler efficiency: in the boiler operation, due to the high temperature of the boiler's external surface, which will lead to more heat loss, through the installation of insulation can effectively reduce heat loss and improve the efficiency of the boiler.
2. Protect the boiler body: the insulation layer can play the role of fire prevention and anti-corrosion, to protect the boiler body from the influence of the external environment.
3. Improve safety: insulation can reduce the temperature of the boiler's external surface to avoid injuries.
Second, the construction of boiler insulation
Common boiler insulation layer structure is mainly divided into the inner (surface) layer, insulation layer and outer (surface) layer:
1. inner layer: the inner layer is closer to the surface of the boiler layer, commonly used materials such as aluminum silicate, clay, ceramic, etc., its role is to maintain the surface finish of the boiler, to ensure that the insulation layer of close fit.
2. Thermal insulation layer: the thermal insulation layer is the core of the boiler insulation layer, generally use mineral wool, aluminum silicate, perlite, etc. as thermal insulation materials, its main role is to prevent heat loss.
3. outer layer: the outer layer is generally used as a thermal insulation board as a material, you can also use color steel plate and other decorative surface, its role is to protect the thermal insulation layer.
It should be noted that, in practice, the construction of boiler insulation layer will be adjusted and changed according to the specific environment and requirements.
In addition to conventional insulation materials, Hongze boiler gas boiler exclusively use of aerospace grade insulation material aerogel (aerogel is a microporous material, its porosity is as high as 99% or more, so it has excellent thermal insulation properties. At the same time, the thermal conductivity of aerogel is extremely low, only 1/2 of glass wool and 1/4 of polyurethane foam, so it can not only insulate, but also save energy), whether it is a hot water boiler or a steam boiler, Hongze industrial boiler can minimize the heat loss, and greatly improve the thermal efficiency of the boiler.
