Removal of combustion gases


Good morning.

CHAPTER II
From the stack, is necessary to provide a condensate collector, equipped with a socket connected to sewage disposal. This accessory is absolutely indispensable for chimneys serving appliances Gas fired, causing many of them large amounts of acid condensation. Also, in bins for liquid or solid fuel appliances, can be formed, especially at home after a long break, some amount of condensate to be discharged properly.
Also in the basket, is indispensable to allow placement of a portal :
- Regular inspection can be done with a flashlight and a mirror or video equipment modern
- Chimney cleaning especially in case of solid fuel, by using specific tools brush, flexible rods, and more specific
.- Removal of material.
Inside a stainless steel chimney will run austenitic stainless steel W430 (AISI 304) with thickness of 0.8 mm. Insulation of a stainless steel chimney will run with mineral wool, high density 40 mm thick. Cotton will be on a base of aluminum foil. Outside of a stainless steel chimney will run ferritic stainless steel polished W 416 (AISI 430) with thickness of 0.5 mm. For all stations connected to the basket or open flame to ensure air needed for combustion and exhaust combustion gases outside, completely and safely, so the room air concentration not to exceed the emissions allowed by the rules of work safety and rules environmental protection. The air needed for combustion is provided in the ratio between the amount of room inside Vi [m] and the nominal flow Qn device use [cm / h:] for the case vi / Qn> / = 30, it is considered that the leak joinery ensure air needed for combustion  ;
case VI / Qn < 30, it provides access directly from outside air through gaps in the lower prevailing room ;
Kitchens are exempt from homes with central heating, there are no other devices use that is allowed access to air from a room by creating an empty neighbor to the room, provided that You meet report / Qn > / = 30, in where Vi is the volume that kitchen plus room volume.
If in neighboring room, for which the gap is provided, installed devices use the ratio of the sum of the volumes of the two chambers [EVI = Vii + Vi2] and the amount of flow devices for use in these rooms [EQn = Qn1 + Qn2] must or, Evi / EQ n > / = 30.
 If this condition is not fulfilled or if sealed with rubber carpentry, air intakes are made directly from outside the building.
 Surface air access opening in a combustion chamber where natural gas is used to determine the product installed in rooms that flow between IQ [m³ / h] and coefficient of 0.0025 [m / cm / h]:
 S = 0.0025 x Qi [m] condition will perform and comply with mandatory.
Combustion air access gap provided at the bottom of the room without locking devices or control. It is forbidden to filling the gap of access of combustion air. A chimney should be as straight as that is no more elbows.


Goodbye !
