Specification before quotation
Calculators, comparison logic and project-input checklists
Use JIELI's tools to convert heat-duty units, estimate preliminary heater size and compare thermal oil with steam. Keep the results with your fuel and operating data when requesting a quotation.
Selection tools
Use these tools to compare boiler quotations at the same useful duty and supply scope. The JIELI THERMAL product catalogue provides model specifications and workshop photographs to review alongside your calculations.
Convert kcal/h, kW and MW without changing physical duty. Enter design margin, LHV efficiency and your own gas or diesel heating value to compare preliminary fuel input. Visible formulas and a worked example explain the result.
Calculate heater duty and fuel consumptionCompare phase change, system pressure, temperature range, water treatment, condensate, control response and typical process fit.
Choose the heating mediumFor gas-fired or biomass-fired thermal oil heater selection, record useful duty, outlet and return temperature, process flow and fuel analysis. Thermal fluid heater and thermic fluid heater enquiries need the same hydraulic and fluid-temperature checks.
Open the eight-input checklistSize a gas-fired or biomass-fired steam boiler from normal and peak steam demand, pressure and feedwater conditions. Compare burner or grate scope, condensate return, emissions and site assembly before comparing prices.
Build the steam boiler selection basisEstimate unrecovered saturated-condensate sensible heat from 2 to 12 kgf/cm² gauge pressure. Compare fuel-equivalent losses in US dollars per tonne and per hour using the stated assumptions; actual return temperature and recovery rate matter.
Open condensate analysisHow to use the results
Keep useful output separate from fuel input. Record annual operating hours, part-load demand, fuel heating value and efficiency basis alongside capital cost. Include electricity, thermal-fluid replacement or water treatment, maintenance and local installation when comparing operating cost; a heater-body price alone is not a system quotation.
Engineering review
Share duty, temperature or pressure, fuel, process, operating hours, emissions requirements and project country.
