What performance factors should be checked before purchasing a dzl coal-fired hot water boiler?

When comparing a DZL coal-fired hot water boiler, customers should not only check the price. The performance breakdown of DZL-1.4 coal-fired hot water boiler and DZL-2.8 coal-fired hot water boiler should include heating capacity, working pressure, thermal efficiency, fuel consumption, grate operation, flue gas system, water circulation safety and maintenance requirements.

For coal-fired hot water boilers, coal quality has a direct impact on combustion performance. The calorific value, volatile matter, ash content, moisture and sulfur content should be provided before technical selection. Based on these data, ZOZEN engineers can check whether the furnace structure, grate area and air distribution system match the actual fuel.

The DZL coal-fired hot water boiler can be equipped with dust removal and flue gas treatment systems according to local standards. The control system can monitor water temperature, pressure, fan operation, grate operation and safety signals. These details help keep the boiler running under designed working conditions.

For buyers planning to purchase 2-4 pieces of DZL coal-fired hot water boiler, it is advisable to provide the heating area, project location, winter temperature, coal specifications and installation schedule. ZOZEN can then prepare the equipment breakdown, performance data and boiler catalog for technical review.
