Also‚ if the ducts are not kept clean‚ such as mold growing in them‚ or too much dust. Furnaces‚ should be professionally cleaned once a year by a furnace expert. Car air conditioning follows most of the same principles‚ regarding comfort‚ safety of driving and mold. They should be used once or twice a month year round‚ just to keep the airflow

Types of Boilers A wide range of options Boiler systems are classified in a variety of ways. They can be classified according to the end use‚ such as foe heating‚ power generation or process requirements. Or they can be classified according to pressure‚ materials of construction‚ size tube contents (for example‚ waterside or fireside)‚ firing‚ heat source or circulation. Boilers are also distinguished by their method of fabrication. Accordingly‚ a boiler can be pack aged or field erected

engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone. The fuel is in contact with the particles and effective mixing and combustion allows good efficiency and low emissions

were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns‚ avoiding the wasteful heat-up and cool-down cycles of the batch kilns. The first were simple shaft kilns‚ similar in construction to blast furnaces. These are counter-current shaft kilns. Modern variants include regenerative and annular kilns. Output is usually in the range 100-500 tons per day. Counter-current shaft kilns The fuel is injected part-way up the shaft‚ producing maximum temperature
