(2) , hang build by laying bricks or stones of the brick, wall that tear open blaze to build when condole when need machines a brick, condole hangs what condole aperture of the brick machines to cooperate clearance to not be more than 5mm, the ply of the wall that tear open blaze is less than 90% . What condole hangs a brick is main place getting power must not have flaw.


(3) , the surprise that contains fixed bolt aperture brick, chase a dry platoon to try step first, it is after the position that bolt aperture indicates on pipe, just can solder fixed bolt. The nut when build by laying bricks or stones is built cannot be twisted too closely, lest damage firebrick, fireproof Tong fill and level up is used inside bolt aperture.


10, boiler setting expands seam stay set:


(1) , boiler setting expands seam stay set the position, form to press design demand, width does not allow to be less than design requirement measure, seam inside forbid to the good thing such as brickbat is dropped. Expand seam inside stuffing asks by the design ram is close, when using asbestine rope, to blaze face the first must want to had immersed fireproof slop.


(2) , canal of wall of the water-cooling that wear a wall, drop canal of canal, header, blowdown, drum, measure lukewarm aperture (canal) reach put aside bridge to wait, osculatory metope place and freely of firebrick boiler setting join place stay expand seam, had better use asbestine rope to twine.


(3) , boiler setting expands seam stay set pattern:


Office of ① , corner expands seam stay set pattern, see a picture 9 (A) : 1/2 brick has sex with 1 brick place stay set pattern; Graph 9 (B) : 1 brick has sex with 1 brick place stay set pattern.


The ② , wall that tear open blaze two end and boiler setting join place expand seam stay set pattern, see a picture 10.


③ , boiler setting is mid and perpendicular expand seam stay set pattern, see a picture 11.


④ , roof and condole hang arch two end and boiler setting join place expand seam stay set pattern, see a picture 12.


Level of ⑤ , boiler setting expands seam use special shaped brick commonly, when be like as good as brick, adopt a plan 13 means build by laying bricks or stones is built. The level when build by laying bricks or stones is built expands seam asbestine rope to want impaction; The level expands seam above firebrick alone build by laying bricks or stones builds height not to exceed 1m, firebrick and red brick rise alternately, lest asbestine rope is compressed,cause boiler setting to tilt.


(4) , perpendicular expand seam the build by laying bricks or stones that hang a line to build, wrong tooth does not exceed 3mm, expand seam inside asbestine rope is more than slightly expand seam stay set width 3~5mm, press at the same time when build by laying bricks or stones is built.


11, bricky build by laying bricks or stones builds firebrick, heat preservation not to allow the brick wringing, before red brick build by laying bricks or stones is built, must water outside coming, work inside saturated.


12, the brick is machined on the style of build by laying bricks or stones that forbids to had been built in build by laying bricks or stones or walk, prohibit the side of blaze of treatment face front the brick.


13, surface of firebrick, red brick all is gotten

Tick off seam

. Convection check is in thick and fast and boiler accessory blocks a part, must scrape grey ear along with build by laying bricks or stones.
