Heating furnace should undertake drying-out after new hero or overhaul. The purpose is slow eliminate build by laying bricks or stones moisture of stockpile of the place in building boiler setting course, make fireproof puddle gets sufficient agglomeration, lest because of,be in when unit go into operation inside the chamber of a stove or furnace warm up quickly, water divides a large number of vaporization, bulk expands and cause body of heater to liner produces crackle or be out of shape, boiler setting splits or collapse.
One, drying-out
Drying-out operation needs to emphasize an attention at 2 o'clock:
(Before 1) drying-out, want to connect vapour according to the technological process that provides to radiation from convection canal, put empty department eduction from radiation canal. The purpose is protective heat pipe, prevent furnace to be in charge of 1000 burn.
(2) warms up speed wants strict according to warm up the curve undertakes, prevent temperature jump, light.
2, start working
(1) reachs cop of accessory equipment, craft, appearance to wait to the component of furnace have comprehensive examination, ensure technological process is not had by accident. Equipment reachs component to answer in good condition and all ready.
(2) belongs to craft cop, equipment to need to furnace system place with vapour be well versed in, ensure craft cop is expedite, do not put inside equipment sundry. Before be well versed in, want to shut appearance down-lead, place of machine pump entrance should add screen pack. When be well versed in, vapour is measured by small arrive to increase gradually greatly, condenser water wants to be given off in time, prevent water to attack.
(3) equipment and conduit try pressure, the purpose is examination construction quality, whether is examination equipment put in blemish and hidden trouble. Zhengzhou flourish fills what fireproof material serves as major to be able to bear or endure the product of fireproof heat preservation that material produces manufacturer to be able to produce more than 40 kinds of different types, product type basically is from sort and recipe scale undertakes distinguishing, line of the products is various, basically can satisfy show level boiler, what steel-making chamfer place needs is high temperature resistant requirement, product quality is worth your reliance.
