High temperature, high efficiency and long life hot blast stove. Sinotec introduced a new type of hot blast furnace
Hot blast furnace production Hengshui CIGNA machinery limited company of science and technology R & D design, is a kind of fuel (natural gas, oil and coal) energy released through combustion into hot air source equipment.
It is different from the steam boiler, stove, there is water and oil as the medium conditions, a heat source device to directly obtain high temperature hot air system needed to air heat exchanger.
According to the different degrees of purity of the output hot air medium, the hot blast stove can be divided into two kinds of direct fired hot blast stove and indirect hot blast stove.
The heat medium blast furnace of direct combustion output for fuel combustion flue gas directly produced, suitable for high temperature, air cleanliness requirements for air drying is not strict.
Indirect heat transfer hot-air furnace is suitable for drying the materials do not allow contaminated areas, the principle is the full combustion of fuel in the combustion chamber, the hot flue gas after combustion, the high efficiency heat exchanger, the heat exchange for fresh through the early, middle and high efficiency filter temperature of cold air, through high pressure fan the system is equipped with the temperature of the air bearing according to the certain operating gas velocity transported to the drying facilities, complete the process requirements for drying dehydration on required drying products.
The hot air stove of Hengshui CIGNA Machinery Technology Co., Ltd. design is divided into two kinds of vertical and horizontal type. Compared with the conventional hot blast stove, the furnace has the characteristics of full combustion, high heat exchanging area, high heat exchange efficiency (80%), low heat energy consumption and long service life (68 years).
All hot air furnace design, according to the required temperature, air volume, pressure drop and other parameters of the auxiliary equipment designed separately, so that each hot stove can be suitable for specific conditions, so as to achieve the best operating results. According to the theory of thermal optimization design of the adiabatic combustion chamber, according to heat transfer optimization design "wrong finned array", according to the fluid mechanics optimization design of the "internal head", the furnace integrates combustion and heat exchange in one, using the indirect heating technology of the latest, make full use of high temperature radiant heat, smoke and air travel counter flow heat exchange, tail gas after the dust emission.
Due to the high temperature protection and air preheating principle, so that the service life is greatly prolonged and tubular furnace, flue gas using longitudinal flow heat sink, negative pressure smoke exhaust mode, the part of heat exchange and not fouling, long time without cleaning, thermal performance is more stable.
Can use all kinds of coal, firewood for fuel, and with two times into the wind device, burning more fully. Fast heating up, high thermal efficiency, the average thermal efficiency of more than 80%; simple operation, long service life
