Diesel Fire Pump Exhaust Pipe Material

Remember do not use galvanized or copper pipe for vent or fill connection pipes on diesel tanks.

Diesel fire pump exhaust pipe material.

Minimum sizes are based on the engine and tank being no more than 10ft 3 3m apart. Exhaust temperature compared to diesel engines. Most blankets will be. A guard pipe protection or approved.

1 blended fuel or jet fuel have a lower cetane ratings which reduces the power output by 10 of the engine compared with the listed power. Exceeding these limits can cause poor performance fuel pump failure and lack of fire protection. Some manufacturers state the exhaust temperatures will appr oach 1000 f. Exhaust pipe insulation 12 water ingress prevention.

For the purposes of driving a fire pump a diesel engine should run at or near its rated speed so that the fire pump produces the desired flows and pressures. Residual fuels domestic heating furnace oils and drained lubrication oils shall not be used. The manufacturer states that the exhaust temperature will be about 1100 f. The project requires this pump to be on the interior so i need to be concerned with the fire risk of the hot surface.

Minimum exhaust pipe diameter is based on 15 feet of pipe one elbow and a silencer pressure drop no greater than one half the max. The selection and installation of such suction pipe material is addressed by nfpa 24 which specifies the use of certain types of iron steel concrete plastic and copper. Nfpa 37 applies for the fuel tank for the fire pump. Layer of material with a thermal cloth outer layer.

When a diesel generating system is activated it is designed to quickly provide power to pumps blowers elevators and other equipment. Exhaust system 2800 3000 c13414 rev b 3300 3600 based on nominal system. The high heat put out by the exhaust is a hazard to occupants and can greatly contribute to overheating the room itself. Flow analysis must be done to assure adherance to system limitations.

Nfpa 20 2013 edition section 11 5 covers engine exhaust and should be carefully reviewed. The i o data for each engine gives a minimum size for supply and return fuel line size. The most common types of steel used in exhaust systems include ferritic and austenitic stainless steels as well as various grades of aluminized steels exhaust system materials are exposed to a variety of harsh conditions and must be resistant to such degradation mechanisms as high temperature oxidation condensate and salt corrosion elevated temperature mechanical failure stress. The exhaust from a diesel engine driving a fire pump is an often overlooked item.

Due to these high exhaust temperatures some models. This causes the temperature of the exhaust gases to rapidly change from ambient to 700 f or higher.
