1. Chain belt grate. The chain belt grate is a wide circular chain belt which is surrounded by and supported on the the front and rear axles via the chain wheels. At present, ZOZEN packaged chain grate steam boiler mainly adopts the large-block chain belt grate with a capacity of 1-20 tph.
2. Scale grate. The scale grate has many advantages. The obvious one is that there is less coal leakage. The scales can be replaced without shutting down the boiler. The ventilation is balanced, and the ventilation section is relatively small (6%). The chain grate bars only bears the stress or high temperature instead of both of them, which improves the working conditions of the chain grate.
3. Beam grate. Its main feature is that the width and length of the grate can be extended in a wide range, and the tonnage of the boiler can be larger. At present, the tonnage of the domestic beam chain grate steam boiler can reach 240 tph. The grate is featured with long service life, good durability, smooth arrangement and convenient replacement.

a Gas detection probe selection point should be within the range of 1m in the vicinity of the valve, pipe interface, outlet port or leaky place, as close as possible, but do not affect the operation of other equipment, while avoiding high temperature and high humidity environment, to avoid External influences such as splashing water, oil, and the possibility of mechanical damage.
b The installation method of gas detection probes can be roof-mounted, wall-mounted or bobbin-mounted. Ensure that the installation is solid and reliable, and that maintenance and calibration should be considered.
c Gas detection probe wiring should use three-core shielded cable, single wire diameter greater than 1 square mm, shield layer must be grounded when wiring.
d When the gas detection probe is installed, the sensor should be fixed down, the lock nut should be fully tightened, the probe cover should be completely covered, and tightened with screws to meet the explosion-proof requirements.
e gas detection probe should be connected under power off conditions, determine the correct connection after the power; should determine the site without flammable gas leakage, open the lid debugging probe.
f The probe should be mounted in a position where there is no large vibration and the temperature is as stable as possible.
g Gas detection probes should be calibrated at least once a year to ensure detection accuracy. Probes are prohibited from pure gas tests.
h When the probe is counted from the user's hands, the warranty period is one year. After the warranty period expires, the company can provide paid services. If the damage to the probe is not covered by the warranty due to improper use by the user, the cost may be charged and repaired or replaced as the case may be. 
The chain grate is the combustion equipment of coal-fired steam boiler. There are three main types and structures: chain belt grate, scale grate and beam grate.
