Explosion-cov qhov rooj pov thawj, tseem hu ua blast- cov qhov rooj tiv thaiv lossis lub qhov rooj armored, yog cov cuab yeej tiv thaiv tshwj xeeb uas siv los tiv thaiv kev poob siab ntawm kev tawg. Lawv feem ntau yog siv nyob rau hauv siab - thaj chaw muaj kev pheej hmoo xws li hluav taws xob, tshuaj lom neeg, thiab kev lag luam roj av. Lawv yog ua los ntawm boiler steel daim hlau, armor steel daim hlau, los yog tshwj xeeb muaj steel daim hlau, nrog lub qhov rooj ncej welded los ntawm channel steel. Nruab nrog tawg- pov thawj sab saum toj thiab hauv qab lub log log thiab cov ntaub qhwv pob zeb ntim cov khoom, lawv muaj kev sib khi thiab kev sib cais, tiv thaiv kev sib kis ntawm kev phom sij tawg thiab ua kom muaj kev nyab xeeb ntawm lub tsev sab hauv.
Raws li lawv cov qauv, cov cuab yeej no tau muab faib ua viav vias - hom thiab rupture- hom diaphragm: viav vias - hom qhov rooj yog ua los ntawm cov hlau cam khwb cia, nrog lub qhov rooj npog coated nrog cov cua sov- cov pob zeb tiv taus, thiab tuaj yeem rov pib dua; lawv feem ntau yog ntsia rau ntawm lub qhov cub phab ntsa ntawm lub combustion chamber. Rupture-diaphragm hom qhov rooj siv asbestos cement board los yog hlau cov ntaub ntawv raws li cov tub ntxhais thiab feem ntau yog ntsia rau hauv lub flue. Kev tawg-cov ntaub ntawv pov thawj qhov rooj tiv thaiv kev poob siab yoj lub zog xws li 0.021 MPa txog 0.19 MPa, thiab tau muab faib ua qib I-IV raws li qib kev puas tsuaj. Deformation raug tso cai thaum lub preset siab tshaj, tab sis cov khoom ua haujlwm raug tswj xyuas. Kev teeb tsa yuav tsum tau muab tso rau hauv cov khoom siv hluav taws xob, ua ntej thiab tom qab cov kiv cua kiv cua, thiab lwm yam, thiab nruab nrog cov kav dej siab pab. Kev tshuaj xyuas phau ntawv tsis tu ncua yog tsim nyog los tiv thaiv xeb. Lub qhov rooj hinges yog kab nrog bronze bushings thiab muaj roj hmab ncoo nyob ib ncig ntawm lawv los tiv thaiv kev sib txhuam sparks, thiab lawv kuj muaj tus kheej - kaw qhov system thiab khiav khiav ceev.
