Thermal insulation of the boiler is to reduce the loss of heat inside the boiler and ensure the normal operation of the boiler at high temperatures. When the temperature inside the boiler reaches a certain value, the medium inside the boiler will vaporize and expand, generating a large amount of heat. Without insulation, this heat will be lost from inside the boiler to the external environment, resulting in reduced efficiency of the boiler and even dangers such as explosions.

In addition, the thermal insulation of the boiler can also prevent the medium inside the boiler from deteriorating due to excessive temperature. If the temperature inside the boiler is too high, some components in the medium will undergo chemical reactions and produce harmful substances, which will not only reduce the efficiency of the boiler, but also cause pollution to the environment. Therefore, in order to ensure the safe and efficient operation of the boiler, the boiler must be thermally insulated.

Boiler insulation system is a key energy equipment, which plays a vital role in industrial production. Thermal insulation layer is the core part of the insulation system, which plays a huge role in improving the energy efficiency of the boiler and saving energy.

The choice of thermal insulation is a primary design consideration. Commonly used insulation materials include thermal insulation materials and fireproof materials. Commonly used thermal insulation materials include rock wool, polyurethane, aluminum silicate, etc. These materials can keep the temperature inside the boiler at a relatively low level and prevent the medium inside the boiler from deteriorating. Commonly used fireproof materials include perlite, mineral wool, rock wool, etc. These materials can effectively prevent the spread of fire and protect the equipment and materials inside the boiler from damage. Compared with these traditional thermal insulation materials, melamine foam, as a new environmentally friendly insulation material, has more advantages. Because it combines excellent sound absorption properties, flame retardant properties, thermal conductivity properties, wide weather resistance, chemical resistance, light weight, environmental protection and good secondary processing and molding properties.

SINOYQX Melamine foam is a three-dimensional grid structure with 99% openings and the length-diameter ratio (L/D) of the grid is between 10-20. The fine three-dimensional grid structure can effectively prevent the convective heat transfer of the air, coupled with the unique low thermal stability, it has a good thermal insulation effect (thermal conductivity, 0.035 W/(m*K)), Become an irreplaceable lightweight thermal insulation material. Melamine foam is a thermosetting organic plastic and has a high degree of fine three-dimensional network cross-linked structure. Compared with polyethylene, polystyrene thermoplastic materials and polyurethane materials with a lower degree of cross-linking, it has high & low temperature thermal stability and aging resistance, can work under the conditions of negative 180 degrees Celsius to 200 degrees Celsius for a long time, and can withstand high temperatures of up to 240 degrees Celsius without decomposition and deformation; but (polystyrene, polyurethane and other foams have a working temperature of only 80 degrees Celsius, and deformation and decomposition will occur when they exceed 80 degrees Celsius). So, it is suitable for use in high-temperature environments in boiler rooms.

Additionally, melamine foam has excellent sound absorption properties. Melamine foam is a three-dimensional grid structure system with fully open cells, with an open cell rate of over 99%. This allows sound waves to easily and effectively enter the deep layers of the foam body and transform into vibrations of the grid to be consumed and absorbed, and can effectively eliminate reflected waves, especially with outstanding absorption characteristics for mid- and high-frequency noise. It can effectively absorb the noise generated by the boiler and create a good working environment.

Therefore, in order to ensure the safe and efficient operation of the boiler, thermal insulation needs to be done, and the insulation layer with poor insulation materials needs to be optimized.

Optimizing the insulation layer structure can effectively reduce the loss of heat energy and improve the energy efficiency of the boiler. Improving boiler energy efficiency can not only reduce energy consumption and energy waste, but also reduce production costs and improve economic benefits.

The optimized design of the boiler insulation system can reduce the operating temperature and stress of the boiler, reduce the damage caused by thermal stress to the equipment, extend the service life of the boiler, and improve the reliability and stability of the equipment.

Optimizing the insulation layer structure can reduce the loss of flue gas temperature and thermal radiation and reduce environmental pollution. The optimized design of the boiler insulation system complies with environmental protection requirements, reduces pollutant emissions from coal burning, and protects the ecological environment.
