When temperatures are expected to exceed 104 degrees F (40 degrees
C), the upper operating limits of all equipment must be carefully analyzed.
Combustion Air Inlets. In large indoor heating plants
10.8.2.2
air inlet shall be taken below the plant ceiling. Preheat of the
outside air
shall be as required to avoid excessively low temperatures in the
air
preheaters or to the boilers. If excessive air is drawn from the
plant,
operator discomfort and possible freezing of piping may occur.
Equipment. Roof ventilators and/or fans must be multiple speed and
10.8.2.3
thermostatically controlled. These types of units are most effective in
maintaining desired conditions with the least consumption of energy. A
motorized damper shall close when fan is not operating.
Design. Provide means to circulate stratified heat collecting near
10.8.2.4
the ceiling to lower levels.
Construction of the building and boiler setting affect building air
infiltration. Considerable energy can be saved by limiting air infiltration
beyond normal ventilating requirements. The building shall be oriented,
constructed, and weatherproofed to minimize air infiltration. The stack
effect due to density differences between air at different temperatures should
be minimized in winter.
Drainage. Drains which may be contaminated by coal or oil shall be
10.9
equipped with separators to separate the contaminates from drainage before
discharging to the sewer. Provide drains and connect to sanitary sewer for:
a)
Pump bases.
