Possible reasons for incomplete combustion in biomass boilers may include the following aspects:
Poor fuel quality: Low-quality biomass fuel, such as high moisture content and uneven particle size, can affect the combustion process. Fuel with high moisture content can lead to reduced combustion temperature and incomplete combustion.
Insufficient air supply: Air is essential during the combustion process. If there is insufficient air supply, the fuel cannot react fully with oxygen, resulting in incomplete combustion. Possible causes include blocked air intake, fan failure, etc.
Unstable combustion system: The instability of the combustion system may also lead to incomplete combustion. For instance, improper adjustment of the burner or an unreasonable design of the combustion chamber can both affect the stability of the combustion process.
Insufficient combustion temperature: Low combustion temperature can lead to incomplete combustion. Possible causes include improper adjustment of the burner and unstable fuel supply.
Ash accumulation in combustion chamber: Ash buildup in the combustion chamber can affect the combustion process, obstructing fuel and oxygen contact, leading to incomplete combustion.
Insufficient combustion time: Inadequate combustion time may also lead to incomplete combustion. If fuel stays in the combustion chamber for too short a period, it cannot burn fully, resulting in unburnt fuel residues.
Inadequate combustion chamber design: An improperly designed combustion chamber, such as one that is too large or too small, hinders the full mixing of fuel and oxygen, leading to incomplete combustion.
Above are some possible causes of incomplete combustion in biomass boilers, which require analysis and resolution based on specific circumstances. Regular maintenance, rational fuel selection, and optimization of the combustion system, etc.

Transforming coal-fired boilers into biomass boilers offers the following benefits:
Environmentally Friendly: The fuel used in biomass boilers comes from organic matter such as plants, animals, and microorganisms. Compared to coal-fired boilers, biomass boilers produce less carbon emissions during combustion, reducing greenhouse gas emissions and being more environmentally friendly.
Energy-saving and emission reduction: Biomass boilers, with combustion technology and a heat recovery system, enhance energy utilization efficiency and reduce energy waste. Moreover, the combustion of biomass fuel generates less ash and pollutants, thus minimizing environmental pollution.
Energy Security: Biomass, as a domestic renewable energy source, can reduce dependence on imported energy and enhance energy security. In areas with scarce resources, switching to biomass boilers can provide a reliable energy supply.
Economic benefits: Biomass fuel is relatively cost-effective, reducing energy costs. Moreover, the technology and equipment for biomass boilers are continually developing and maturing, making them more economically competitive.
Waste Utilization: Transforming coal-fired boilers into biomass boilers can utilize agricultural by-products such as straw and wood waste, effectively utilizing waste resources and reducing resource waste.
It's important to note that converting coal-fired boilers to biomass boilers requires corresponding technical upgrades and equipment updates, including the combustion system, fuel supply system, and flue gas treatment system. The conversion process must consider factors such as fuel characteristics, combustion properties, and equipment compatibility to ensure the stable operation of the biomass boiler post-upgrade and achieve the anticipated energy-saving and emission-reduction effects. Therefore, it is advisable to seek engineering technical support and consultation when converting coal-fired boilers.

The occurrence of oil atomization in thermal oil furnaces may be related to the following operations:
Excessive Oil Pump Pressure: If the oil pump pressure of a thermal oil furnace is set too high, exceeding the design specifications, it may lead to atomization. Excessive oil pump pressure can increase the atomization amount through the nozzle, surpassing the combustion requirements within the furnace.
Excessive nozzle orifice size: An oversized nozzle orifice in a thermal oil furnace leads to excessive oil injection, which can also cause oil injection phenomena. The nozzle orifice size should be selected rationally based on the combustion requirements within the furnace and design specifications.
Excessive furnace temperature: The furnace temperature in the thermal oil furnace exceeds the design requirements, which may lead to oil spraying. Excessive temperature reduces the viscosity of the thermal oil, increasing the risk of oil spraying.
Low oil level: If the thermal oil boiler's oil level is too low, the oil pump may intake air, which could lead to oil jetting. The oil level should be maintained within the normal range to prevent the oil pump from drawing in air.
Oil Pump Failure: Faults in the thermal oil furnace oil pump, such as pump blockage or oil leakage from the pump body, may lead to oil spraying. Regularly inspect and maintain the oil pump to ensure its proper operation.
Oil Tube Clogging: Oil tube clogging in a heat transfer oil furnace, caused by the accumulation of impurities or sediments, may lead to oil spraying. Regular cleaning and maintenance of the oil tubes ensure smooth oil flow.
Improper Operation: Failure to follow the correct operational procedures when handling a thermal oil furnace, such as over-adjusting the oil pump pressure or arbitrarily changing nozzles, may lead to oil spitting.

When selecting an appropriate atmospheric pressure hot water boiler, consider the following factors:
Heating Area: First, determine the size of the area to be heated, which will decide the required heat output of the hot water boiler. Generally, the larger the heating area, the greater the heat output needed.
Heat Load Calculation: Conduct a heat load calculation, taking into account the insulation performance of the heating area, indoor temperature requirements, and external climate conditions, to determine the required heat power. You may request a heat load calculation to ensure the selected hot water boiler meets the heating needs.
Fuel Type: Atmospheric hot water boilers can utilize various fuels, such as gas, etc. Choose the appropriate fuel type based on the local fuel supply and cost considerations.
Boiler Efficiency: Focus on the energy efficiency of hot water boilers and select products with higher efficiency. High-efficiency hot water boilers can provide superior heating performance while reducing energy consumption and operating costs.
Boilers and Quality: Choose hot water boilers produced by reputable manufacturers to ensure reliable product quality and comprehensive after-sales service.
Safety and Environmental Protection: Focus on the safety and environmental performance of hot water boilers, choosing products with safety protection features and low emissions.
Budget Consideration: Select a suitable hot water boiler based on budget constraints. In addition to the purchase cost, consider the ongoing operational and maintenance costs.
Considering the above factors, a suitable atmospheric pressure hot water boiler can be chosen to meet heating needs, while achieving good performance in terms of energy efficiency, safety, and environmental protection. It is recommended to consult experts or hot water boiler professionals during the selection process.
