Chain Grate Coal Fired Thermal Oil Heaters

The biomass fuels fired thermal fluid heater is a new trend for its green energy and its large potential supply. Adopting the biomass as the fuel can both recovery the waste energy and save our energy cost. Large type thermal oil heater will delivery as two parts, up parts, and chain grate parts.

Advantage Feature

1-The body structure of Romiter Machinery horizontal square-box boiler is out of the ordinary. which adopts national patent technology with independent intellectual property rights. No dead air in the boiler tube. Convection area cannot burn air-isolated plate and the fire resistant brick on the top cannot collapse, which increase service life of boiler and heat transfer oil.
2-Romiter Machinery square-box boiler may adopt three kinds of chain grate, i.e. :Chain belt type: with simple structure. low steel consumption, high air leakage efficient, high coal leakage volume. suitable to burn I II soft coal; Squama type: with uniform air distribution. lower coal leakage volume, running with rolling friction, low resisting force with endurance, easy and simple replacement of boiler grate, high steel consumption, and high cost, suitable to burn I 11 III soft coal.

3-Rolling type grate: burning coal in rolling mode, with high burnout rate, thoroughly treated side-sealed air, suitable to burn II III soft coal and coal gangue.

4-Adoption of automatic temperature control function is made to achieve stable heating and precise temperature adjustment, which may meet different requirements.

5-It adopts perfect running control and safety monitoring device with safety, reliability and easy operation.

6-Fast packaged or assembled for shipment with easy transportation, short installation period, and fast return of Investment.

7-The boiler features heat preservation performance with high-efficiency heat preservation material and state-of-the-art construction technology, lower radiating loss of boiler wall.

8-Fast temperature rise, high thermal efficiency, with overload capacity at a certain degree to ensure output of boiler.

9-Outstanding energy-saving effect, saving energy by 10-15% compared with similar products, return of investment for the equipment in the whole boiler room may be attained by capital of saved energy for one year operation.

Why choose thermal fluid heater?

The choice between a steam system or a thermal fluid system is governed by the process requirements. The range or process temperature is a deciding factor. If the systems required temperature is above the freezing point of water (32°F) and below approximately 350°F, the choice is usually steam. However, if the required temperature is below 32°F or above 350°F, thermal fluid may be a better solution.

1. Reliability and rugged long life construction ;
2. Guarantee on both the burner and the boiler ;
3. Efficiency, which can be higher than 92% over the operating range ;
4. Investments and maintenance costs reduced ;
5. Optimised heat balance, associates the high output of the boiler with very low thermal losses on the distribution system which means very high overall plant efficiency ;
6. Very short response time, low inertia ;
7. Optimisation of the thermal coefficient of transfer of the boundary layers ;
8. Low pressure of operation normally no more than total system resistance (10 bar max) for high temperature (350°C) ;
9. Well suited for indirect process heating;
10. Compactness ;
11. Safety of the whole system by the installation of dedicated controls and equipment to suit the process requirements (deaerators, temperature monitors and alarms, deaerator relay...) ;
12. No corrosion, therefore, very long plant life.
