UTILIZATION OF THE UNIVERSAL BOILER FOR COMBUSTION OF WHOLE BALES OF HAY
Recently, the attractiveness of energy crops for burning has increased namely in the field of agriculture. This mainly involves burning hay harvested from permanent grass stands, especially meadows and pastures.Universal boiler for burning (not only) whole bales of straw
Biomass-fired boilers with outputs ranging from 100 to 1,000 kW are now mostly designed for either burning straw or waste wood.Biomass boiler room

WATER TREATMENT EQUIPMENT
SOFTENING FILTERS
Building dimensions for footings
The softening filters are used in the field of chemical water treatment and are designed to soften water by a Na+ cation exchanger or for neutral decarbonisation. The water being treated flows through the filter either from top to down or from bottom to top. For softening using the cation exchanger, the bottom-up flow is recommended. The recovery shall be always made in top-down direction. The filter is a vertical vessel welded from steel sheet metal and vaulted bottoms. It is placed on four tube legs. Inside the vessel, there is an upper and lower jet bottom. The vessel is equipped with fittings; inlet, outlet, connecting and delivery pipes, and with pressure gauges. The outer surface of the filter is primer-coated. The softening filters are designated by ZF and by value of filter diameter (D) in mm.
For basic design, connecting and construction dimensions, see the table. Maximum working overpressure is 0.6 MPa. Maximum working temperature depends on a filler applied – max. 90 °C. For washing, clean pressure air must be supplied, with overpressure of 60 – 100 kPa. A bottom layer of washed silicate sand, grading 1.8 to 4 mm, is recommended in filters. The inert filler layer should be 100 mm for filter size 600 to 1,000 mm, 200 mm for filter sizes 1,400 to 3,000 mm.
