Forest fire-fighting machines

Scientists at the University of Forestry in Hanoi have successfully researched forest fire-fighting machines operating in areas with complex terrains. Forest fire extinguishers are local air.

Every year in Vietnam, hundreds of incidents occur, destroying thousands of hectares of forest, in which forest fires often occur in areas with complex terrain, steep slopes, far from water sources, and difficult transportation.

From this reality, Dr. Duong Van Tai and the scientists from the Forestry University designed the windmill designed lightweight and easy to use even in complex terrain.

"The feature of the wind blower is the same as a high-pressure fan, integrated with a gasoline engine specialized in forestry at a speed of 7000 rpm .. With a fan with a special engine, the team The equipment has a very large airflow , " said Tai.

The machine is based on a shaft that is connected to the shaft by the shaft. When the engine is running, it leads to the rotation of the rotor blades.

The blower is specially designed to generate high flow, velocity and air pressure. When blowing air flow and high pressure into the fire, the air acts to dilute the gas concentration down to the point of fire. Fire, while lowering the fire temperature, down below the point of fire, from which the fire is extinguished.

"China has used windbreaks, but with heavy loads, low flow and insufficient pressure, the capacity of wind turbine generators up to 4.5 kW , " the doctor said. Tai added.

A windfight blower can extinguish a fire on the ground, a fire height of 2.5m. This type of fire fighting machine is very good for eucalyptus forests, acacia forests, rubber forests, protection forests. If not using forest fire, remove the blower system, install the system to cut the tree can be used to cut down the wood and bamboo.

The products belong to state key subjects, achieving excellent grades. Currently, the machine is applied in the localities in the Central Highlands and shows high effectiveness of forest fire.
