A: For 5 t/h, ZOZEN Boiler recommends the DZL series biomass-fired steam boiler. The DZL biomass line covers 2–10 t/h, with working pressure options of 1–2.5 MPa and outlet temperatures around 170–225 °C. It’s engineered for steady steam output and reliable operation.
A: Fuel adaptability is a key advantage of ZOZEN Boiler’s DZL biomass units. They can utilize biomass molding granules, wood chips, corn cobs, sawdust, palm shells, and rice husk, helping users le...
ZOZEN’s coal-fired reciprocating grate boilers integrate a suite of primary and secondary emission control strategies to help industrial facilities meet stringent air-quality standards while maintaining high availability. Primary measures begin in the furnace: staged combustion and zoned air distribution reduce peak flame temperatures and oxygen availability in initial zones, suppressing thermal and fuel NOx formation. The reciprocating grate provides controlled fuel residence and mixing, ...
In recent years, the state has stepped up efforts of prohibiting the traditional coal-fired boilers. Major enterprises keep up with the times and purchase various environmental protection boilers. Gas-fired boiler is currently the most popular environmental protection boiler. However, due to geographical limitations in some areas, natural gas is difficult to obtain, or the cost is too high, some enterprises will choose biomass steam boilers.
For the dust removal of biomass boiler, centralized or decentralized dust removal system are generally selected according to the process flow, and available dust can be recovered as much as possible under the conditions of process permission. The core of dust removal system is various types of dust collectors, including bag filter, electrostatic filter and electric bag filter.
EPA has promulgated national emission standards for hazardous air pollutants from three major source categories: Industrial boilers, commercial and institutional boilers, and process heaters. The final emission standards for control of mercury, hydrogen chloride, particulate matter (as a surrogate for non-mercury metals), and carbon monoxide (as a surrogate for organic hazardous emissions) from coal-fired, biomass-fired, and liquid-fired major source boilers are based on the maximum achievable control technology. In addition, all major source boilers and process heaters are subject to a work practice standard to periodically conduct tune-ups of the boiler or process heater.
Agglomeration problem mainly occurs on the fireside in the fluidized bed boilers. Agglomeration is basically the ash-related problem of biomass-fired boilers. Ashes which are formed from high-sulfur and low-ash fuel agglomerate if they are prone to sulfating condition for long time.
The integration of a biomass system is relatively simple. In most cases the systems are retro fitted and replace a fossil fuel boiler. The biomass boiler replaces the existing fossil fuel boiler, but the downstream heating system will remain the same, so there is no need to replace the radiators or whatever emitters are in place.
