7-5. POLLUTION CONTROL EQUIPMENT. The various types of pollution control equipment and
possible regulations are described in chapter 5. Provision may have to be made to keep waste
water streams from the ash and waste receiving and storage areas separate so that they may be
treated before being discharged to the sanitary sewer system. This treatment will undoubtedly
include filtering to reduce the suspended solids, and may include chemical treatment to balance pH
7-6. OPERATION AND ASSOCIATION COSTS. The O&M cost portion of the HRIFEAS computer
program also gives only a very approximate estimate. As part of the final economic evaluation and
preparation of an operating budget for the plant, a detailed estimate of the operating costs of the
plant needs to be made.
(1) Personnel. Incinerator plant operating personnel should be of the same grade and
quality as regular boiler plant operators. Operators should be trained and certified under the tri-
services program for certification through the National Institute for the Uniform Licensing of Power
(2) Responsibilities. Approximately 60% of the operation deals with running the front loader
and feeding waste into the charging hoppers. A comprehensive training program is necessary so
that each person knows how to effectively function as a solid-fuel-fired boiler operator, a solid waste
equipment handler, a maintenance and repair person, and a shift supervisor. In a larger plant,
several people may be required to operate front loaders, to monitor the operation of the
incinerators, and to provide routine maintenance. A 24 hours per day, seven days per week
operation will require an extra "swing" shift of operators. A plant manager will also be needed to
supervise all the operators and monitor the plant operation, and may also be used to record the
weight of waste being delivered.
(3) Size of Operating Crews. Typically, a small incinerator plant (i.e., less than 50 tpd) will
require a minimum of three operations crew members per shift (two operators plus a mechanic who
may be shared with another plant) plus the manager or a shift supervisor. If the facility has a dry
scrubber and bag house, one to two more people per operating shift may be required.
b. Consumable Supplies. Information should be gathered from major equipment suppliers as
to consumable supplies, especially for the gas cleanup system. A detailed list and associated costs
need to be developed. The contractor is required by the incinerator CEGS to submit a list of repair
parts and supplies that will be needed for a number of months of operation.
c. Operation Schedule. Ideally, the incinerator plant should be designed (i.e., sized) to operate
continuously. Minimizing the number of startup/shutdown cycles will prolong the life of the
equipment, especially the refractory insulation in the combustion chambers. Depending upon the
size of the incinerator, especially packaged units, it may be necessary to shut down on the second
shift for an overnight burn-down and cool-off if ash removal is a manual operation.
