Warm bitumen
For heating bitumen at the place of its fence, steam coils are used. The warmed bitumen is fed to the bitumen boilers (provided that the bituminous storage is on the bitumen base) or to the car lines that deliver bitumen to the base (provided that the storage is in a gesture warehouse) using layser pumps. Pumps manufactured under the D-171 brand have a capacity of 400 l/min at the maximum suction height of 2-2.5 m of water. Art. The required engine power is 8-12 liters. With. The indispensable belonging of bases for binding materials is boilers in which bitumen is heated, and with tar materials – heating the components of the tar and mixing them. Operational inexpensive closing of an LLC in Irkutsk.
The following basic requirements should be presented to the boiler plants: 1) the firebox and the lining of the boilers are made so that hot gases were washed the largest surface of the boilers and the direct effect of flame on them is not excluded; 2) for the convenience of operation, boilers should be grouped; Around the boilers should be made bridges with railings and boilers should have lids; 3) branches should be made to each boiler from the trunk bituminous pipeline to pump the binding materials from one boiler to another, provided that interchangeability is interchangeable; 4) fire safety and compliance with safety regulations should be checked for each specific installation; In order to avoid ignition of gases on boiler plants serving for the preparation of tar, the possibility of an open flame enters the upper part of the boiler. The duration of bitumen heating in boilers to 160-180 ° is an average of 5-6 hours; The fuel need is determined in 0.15-0.25 m3 of firewood per 1 m3 of bitumen.
