Industrial kiln technical transformation has the following main ways:
(a) the right to choose combustion devices
(1) the reasonable choice and use of the burner;
(2) promote the use of flat flame, twin flame, high speed and adjustable flame burner, the new energy saving 5 ~ 10%;
(3) solid fuel to adopt mechanized coal and pulverized coal combustion.
(2) the waste heat of flue gas recycling
(1) the use of flue gas preheating combustion-supporting air, can get 15 ~ 25% energy-saving rate;
(2) choose suitable flue heat exchanger;
(3) improve the effect of the use of the heat exchanger;
(4) according to the installation of waste heat boiler heat situation;
(5) reduce the left chamber of a stove or furnace flue gas temperature.
(3) strengthen the furnace insulation
(1) has transformed furnace for refractory brick or lightweight refractory brick and refractory fiber and composite structure of the thermal insulation material;
(2) with composite castable hanging roof, reducing roof heat dissipation;
(3) on the medium temperature discontinuous furnace adopts full refractory fiber lining.
(4) improve the sealing of the furnace
(1) reduce the oven door opening and installation;
(2) USES the castable lining structure and wall plates.
(5) reduce water-cooled heat loss
(1) with or without water, less component, reducing heat loss;
(2) to must be set in furnace thermal insulation bandaging water-cooling elements;
(3) adopt evaporation cooling for recycled water cooling and heat loss, not only can get the medium pressure steam, but also save water.
