Practical Stove Furnace Insulation Panels For Condensing Gas Boiler

Customized vermiculite refractory insulation moulded parts for condensing gas boiler heat cells insulation

Condensing gas boilers

Condensing gas boiler is a new technology products which increased the energy using efficient, and reducing the exhaust gas emission. It is designed to serve for around 15 years, which is a logically energy efficient reducing, environmental friendly and economic products.

The core of the condensing gas boiler is the heat exchange part due to the poor working environment, fast firing and cooling. The refractory and insulation material can not last the designed service life, commonly only works 1-2 years that will damaged inside, which lead the heat exchange unit can not working normally in long years, and requires replacement.

Bluewind vermiculite refractory and insulation blocks, apply natural expanded vermiculite, and inorgainc adhesive, made the 1,200 Celsius degree resistant blocks. With thermal conductivity below 0.28 W/m.K at 800 Celsius, and can continuous working for over 30 days in lab testing, no breaking nor shape changing. In expecting serving for 10+ years.

Description of Vermiculite Board

Features

Refractory grade: Up to 1200 C fire/heat resistant

High thermal shock resistant, can be used on fire side;

Non combustible

Thermal/ Heat insulation: Low thermal conductivity <0.3 W /m.K @ 1,000 Celsius degree

Density range: 0.4-1.2 g/cm³

Chemical resistant;

High mechanical strengths;

Easy for secondary tooling and machining

Environmental friendly

Blue Wind Vermiculite refractory and insulation boards apply 0.3-1 mm expanded silver vermiculite as the raw material, with inorganic adhesive and cold pressing technology combined, after hours drying that made the good strength fireproof insulation boards.

For serving under severe conditions, vermiculite boards have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by vilatile alkaies and some slag.

Stoves applying

For stoves application, it requires lightweight and good fireproofing requirement, as well as thermal shock resistance. The vermiculite boards owns the all benefits and plays an important role in the stoves applying especially in wood stoves and pellet stoves. And our durable vermiculite boards with longer working life can resistant the bending and crushing which caused by long time uneven heating, bring the stoves longer service life and less trouble for the replacement.

Heat cell

Heat cell is the heart part of the condensing boiler, it determines the service life of the condensing boiler.

Vermiculite boards with 1200 C can resistant the extremely environment which fast drying and water soaking; has better performance than the traditional ceramic fiber boards.

Condensing boiler

Condensing boilers ideal service life is about 12-15 years, while the heart part heat cells determines whether it can or can not to reach the ideal life. With high quality vermiculite boards, it can reduce the times of heat cells replacement and bring the user less troubles.

Aluminum Electrolytic Cells

The V-1100 and V-1200 are recommended for the applying of Aluminum electrolytic cells. Their high strength and low thermal conductivity make them ideally for the applying of the industry. Various combinations of bulk density, insulation properties and compressive strength, commonly V-1100(500), V-1100(1000), and V-1200 are chosen for the excellent performance in strength and thermal insulation performance.

And the another important feature in the Aluminum Electrolytic cells is that the V-1100 and V-1200 series do not corrosion by the molten aluminum and are resistant to cryolite penetration and fluorides. It helps to maintain the cells service life and keep the better running of the aluminum electrolytic processing.
