Introduction

> Solid Fuel Coal Fired Boiler
Capacity: 40kw-7000kw 100kg-2000kg/h
Fully automatic coal steam/hot water boiler, kind of fixed grate type coal feeder boiler. It adopts water-tubes & fire tubes design for heat transferring. Thermal efficiency is about 85%.
> Boiler Advantages
1. Complete combustion with high thermal efficiency
Adopt semi-gasification combustion way, negative pressure combustion inner furnace, reasonable proportion of air distribution to reach compelte combusition, make its higher efficiency, and the emission is free of visible smoke and dust.
2. High efficiency
Large heating area, high thermal efficiency, wide range of coal types, strong combustion firepower, good heating effect, 13% more energy-saving than similar products in the industry.
3. One-touch operation, safe and convenient
Equipped with a microcomputer LCD control system, one-button start, press the key, it will enter a fully automatic operation state, safe and convenient.
4. Multiple protection safety guarantee
The product is equipped with high-quality pressure controller, safety valve, multiple protections such as overpressure, low water level and overheating protection to ensure product quality and safe use.
5. Together with cyclone dust collector, reduce emission concentration.
Environmental friendly, obey to local emission standard strictly.
6. Modular delivery, it is installed before delivery.
The coal boiler is installed before delivery. In site, only needs to be connected to the power supply, water inlet/outlet pipe and sewage pipe, help saving the installation cost and installation materials.
> Customized Mobile Boiler
Portable type coal hot water boiler in container. (Heating system customized for any customer needs.)
1. Coal hot water boiler in a container, which is specially prepared for buildings - where there is no enough space for the boiler and fuel room.
2. Containerised mobile type coal boiler plants are fully operational coal heating systems built inside a custom made container with fire-resistant walls. They include a silo, a boiler, the automation and all the electrical works and plumbing already made in the factory. They are easy to install and easy to relocate.
