Horizontal Type Coal/Biomass Fired Thermal Oil Heater

Horizontal Type Coal/Biomass Fired Thermal Oil Heater

The horizontal type coal/biomass fired thermal oil boiler is an safe and energy saving boiler with working characteristics of low working pressure (0.8 MPa) and high temperature (330℃). The combustion equipment could be chain grate or fixed grate, The heat carrier is heat conduction oil, the circulating pump force heat transfer medium circulating in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating. Because of working in liquid state, the coal fired thermal oil heater is safe and reliable.

Owing to its characteristics of high heating temperature, low working pressure, energy saving, the coal fired hot oil heater could be widely used in a variety of industrial heating process. Such as petroleum chemical industry, synthetic fiber industry, textile printing and dyeing, plastic and rubber, paper industry, wood industry, building material, machinery industry, food industry, electrical equipment, coking industry, metal and casting industry, detergent industry, fat and paint industry, carbon industry.

Boilers Structure

Horizontal Type Coal/Biomass Fired Thermal Oil Heater

1. The radiation section adopts square coil, and the convection section section adopts serpentine coil, the coil has good thermal expansibility, low stress, safe and reliable.

2. The combustion chamber is consisted of chain grate and the front & rear arches, large combustion space, the fuel could burn sufficiently and achieve high combustion efficiency.

3. The boiler is horizontal type three pass structure, improve the heat utilization efficiency, decrease the exhaust smoke temperature, and ensure high thermal efficiency.

4. Equipped with safety protection devices to ensure safe operation.

Auxiliary equipment

CHAIN GRATE

CHAIN GRATE

The chain grate is 500~1000mm longer than others, improve combustion efficiency. The grate has small fuel leakage, has long working life.

CONTROL SYSTEM

CONTROL SYSTEM

We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.

Air Preheater

Air Preheater

Air preheater could be equipped to extract the heat form the flue gas, make fuel use of heat, increase thermal efficiency.

WATER PUMP

WATER PUMP

We adopts the stainless vertical pump with low noise, stainless impeller and pump body.

Steam header

Steam header

Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.

Water softener

Water softener

It is fully automatic and free debugging. We adopts PE material for salt tank body, it has hard texture and it is easy to move, anti-shock, and no leakage.

Quality

Zhongding Boiler pay more attention to the boiler quality from raw material to producing process.

boiler quality
we choose domestic well-known manufacturer who can provide component report of raw material, to ensure the raw material is qualified. After the completion of raw material procurement, there are specialized technicians in our factory to make sampling chemical composition analysis and physical performance analysis, and we can also provide raw materials inspection report.
We adopt numerical control cutting, which has the advantage of high precision, neat cutting surface, nice appearance and high material utilization.
Boiler manufacturing
Boiler production
We adopt submerged arc fully automatic welding. When each welding process is done, the 100% X-ray inspection will be arranged for every welding seam, which can prevent the defective parts from flowing into the next process.
