malta anthracite coal fired boiler manufacturer
The heat exchange surface of Fangkuai malta anthracite coal fired boiler manufacturer is reformed reasonably: 1. The horizontal boiler is removed from the furnace arch of the original furnace, and the coal bed is covered with insulation layer and refractory brick, which is transformed into the secondary radiation surface. Vertical boilers can build radiation reactors at the bottom of the furnace and install radiation arches on the upper part of the tank. 2, control the leakage air volume of furnace and flue. It is necessary to seal the boiler's observation hole, to seal the boiler's air duct and flue, especially when the air leakage rate of brick air duct and flue is large, after changing to burning gas, it is necessary to carry on the sealing treatment, preferably to change to the metal flue. When multiple boilers share a total flue, each boiler Breakers should be installed on the flue to prevent flue gas and residual gas from the purging process from flowing into the boiler furnace that has ceased to operate. Reasonable selection of burners for Fangkuai boilers: 1. Under rated gas supply pressure, the thermal load of the burners must meet the requirements of the boilers. Combustion is complete, excess air coefficient is low, combustion temperature is high, combustion noise is small, furnace flame fullness is good, flame radiation ability is strong. 2, the load regulation ratio meets the requirements of boiler operation, and the excess air coefficient can be adjusted. 3, can realize the boiler safety technical supervision regulations issued by the Ministry of Labor automatic control project.
In the transformation process, side by rapid technical engineers FGR advanced combustion technologies, the use of flue gas recirculation and the outer loop is provided, withdrawing part of flue mixed with the combustion air, and then into the furnace through a burner, not directly part in the combustion, by reducing the effect of the combustion flame temperature to reduce the temperature and oxygen concentration, to achieve the purpose of reducing NOx generation. For now, for a large volume of gas malta anthracite coal fired boiler manufacturers, low compared to the overall transformation of nitrogen to replace the boiler equipment will save a lot of costs. Fast boiler has a boiler in research and technology low nitrogen aspects of considerable industry experience, successful completion of the reconstruction project Dingzhou low nitrogen Erie boiler, significant cost savings for businesses.
Select the appropriate malta anthracite coal fired boiler manufacturer fuel and combustion forms: the most consumed fuel in use is the boiler, energy-saving measures to do first of all have to start from the choice of fuel. In the current economic conditions, there are three main boiler fuel, namely the solid fuel, liquid fuel and gaseous fuel, three different heat generated by the fuel which is not the same, the degree of harm to the environment is not the same. On the whole, in terms of heating fuel gas quality or environmental protection has a significant advantage in the choice of fuel should be preferred. Heating boiler in some systems because of the influence the production process and the fuel supply capacity, the choice of gaseous fuel is also subject to certain restrictions. In the selection of fuel, because the high cost of this choice of fuel in the boiler heating costs tend to be higher. Is more feasible briquettes may be employed, it will be used after vaporization, the residue after burning so that less amount of the exhaust gas is small too heavy discharged from the combustion, and the combustion heat value of the coal after vaporization is relatively high, so the use of more cost-effective in the heating boiler.
Coal fuel size in CFBC malta anthracite coal fired boiler manufacturer
CFBC uses crushed coal of 3 to 6 mm size.This requires only a crusher not a pulverizer.From storage hoppers Conveyer and feeders transport the coal to feed chutes in the furnace. Start up is by oil burners in the furnace.Ash spouts in the furnace remove the ash from the bottom of the furnace.
