Customized Refractory and Insulation Block for Condensing Gas Boiler Heat Cell

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.
