Central heating is the heating method with the lowest heating cost. Therefore, more and more towns, industrial parks, and communities adopt central heating. The residential area of ​​150,000 square meters intends to purchase biomass boilers for central heating.

1. Selection of biomass boiler
The selection of heating boiler is to determine the boiler type, and the other is to determine the boiler specifications and parameters. Let’s first look at the 150,000 square meters of biological boilers that require several tons.

Generally speaking, the heating area of ​​a 1 ton hot water boiler is 10,000 square meters, and 15 tons of biomass hot water boilers are needed for heating 150,000 square meters. However, considering that the customer is located in the Northeast region, in order to fully meet the heating demand, the heating area of ​​a 1-ton boiler is calculated at 7,500 square meters, and 150,000 square meters requires 20 tons of biomass hot water boilers.

2. Biomass boiler parameters
Two options can be considered for a 20-ton biomass hot water boiler.
One is to purchase two 10-ton DZL chain grate boilers;

The second is to purchase a 20-ton SZL chain grate boiler.
